    Unmanned systems updates

    Some people may have anticipated that the unmanned aircraft industry, amid initial exuberance over the new technology and the impact it has made, would eventually suffer some sort of implosion. Nevertheless, while some smaller players have come and gone, by and large new companies are still sprouting, and other start-ups may have been absorbed by bigger fish with more resources.

    DroneDeploy acquired a couple of software image acquisition and robotics companies in recent years – both StructionSite (2022 acquisition, San Francisco) and Rocus (2021 acquisition, New Zealand) are now part of DroneDeploy, widening their jointly addressable markets.

    Drone Delivery Canada (DDC) is in the process of merging with Volatus to bring a combined service and equipment capability to market. Both companies are currently listed on the Toronto Stock Exchange and will trade under DDC’s stock symbol “FLT” following the completion of the merger, anticipated by the end of Q3 2024. DDC provides a unique Condor cargo UAV capability, remote operations center, cargo infrastructure and operations software, while Volatus provides UAV services, training and equipment sales to enable a path to market for the combined company.

    Joby has been a leading participant in the emerging eVTOL air-taxi market segment, and acquired radar developer Inras GmbH in Linz, Austria in December 2021. The small Inras team brought advanced radar technology to Joby’s eVTOL development to provide onboard sensing and navigation.

    Now Joby has also acquired the autonomy division of Xwing, which brings, according to the Joby website, “autonomy, including vision system processing, detect and avoid algorithms, mission management and decision making, ground control stations, remote operations and also the integration of Artificial Intelligence (AI) and machine learning algorithms.”

    The Xwing Superpilot software has previously enabled autonomous ‘gate-to-gate’ flight, 250 self-contained flights and 500 auto-landings with a Cessna 208B Grand Caravan for demonstration/tests. This system resulted in an official project designation for the certification of a large unmanned aircraft system (UAS) by the Federal Aviation Administration (FAA) in April 2023, and an Air Force Military Flight Release in 2024. Joby expects the acquisition to not only further long-term autonomous civilian capability — initial FAA certification is anticipated with piloted aircraft — but also to support existing and future business with the United States Department of Defense (DOD).

    Meanwhile, Airbus is taking a similar approach by teaming with Helsing in Europe to integrate AI into a future Airbus unmanned Wingman concept aircraft — a UAV designed to fly with and be controlled by front-line manned fighter aircraft. Alongside growing European force requirements, Airbus envisages a lower-cost, attributable, UAV commanded by manned aircraft that could dispatch the Wingman for target reconnaissance and destruction or electronic jamming and deception of enemy air defense systems.

    Both Joby and its rival Archer have also received FAA Part 135 certification, which allows them both to run an air-taxi operation. Neither has yet obtained FAA authorization for their eVTOL aircraft, but both appear to have a clear mandate from the FAA for the steps necessary for those certifications. Both intend to operate existing certified fixed-wing aircraft as air taxis in the meantime under the Part 135 authorization.

    While browsing through the FAA’s Special Class Airworthiness Criteria for the Joby Aero Model JAS4-1 Powered-Lift, published on the Federal Register, I learned that the task to certify a brand-new category of aircraft is huge — not big, absolutely gigantic.

    FAA put together a draft of proposed cert criteria and put it out for comments to interested government agencies and industry — a whole slew of comments were received, which the FAA reviewed. The FAA incorporated some and discarded others. Just the response to these comments goes on for many pages — there were a lot of comments. Nevertheless, just skimming through FAA’s responses to these comments was a significant undertaking, never mind reviewing and understanding the basic requirements for, say, the two-performance option. Imagine what eVTOL operators have to go through to demonstrate that they meet the steps to achieve FAA certification.

    The cert basis for Joby appears to be a combination of fixed wing and helicopter requirements, plus more to address the novel electrical propulsion system and the batteries that provide its power. Two levels of performance standards are set out — an “essential” level and an “increased” level. The 42 organizations that commented on the draft requirements included worldwide aviation agencies, eVTOL and aircraft companies, industry associations and major components suppliers, the Association for Uncrewed Vehicle Systems International (AUVSI) and some individuals — a huge group of involved and impacted organizations.

    Joby applied to the FAA in November 2018 for certification of its Model JAS4-1 powered-lift eVTOL. Joby has been supporting just the activity related to certification for six years to date. All the other eVTOL developers are at a very similar stage as they try to get their aircraft into service carrying people and generating income.

    Most eVTOL developers have major sponsors familiar with the certification process. Otherwise, the effort would just be too costly, never mind the cost of proving the capability to operating customers, the country as a whole and capturing the imagination of intended users. Plus, of course, building and qualifying the test vehicles, and the operational infrastructure to allow these eVTOLs to land, pick up customers and fly them to somewhere near their destination. The length of time to do this over so many years has broken many unwitting start-up companies. Achieving this goal can be incredibly difficult without the substantial financial resources of major companies such as Airbus, Boeing, or major airlines.

    Moving from UAV to passenger airplane is something not to be taken lightly. As a potential future passenger, just keep waiting for your first flight in an operational certified eVTOL. Several of the contenders have targeted 2026, but who knows? I wish them the best of fortune and they’ll need it!

  • UAVs evolving into air taxis

    UAVs evolving into air taxis

    One of several derivative branches from unmanned air vehicles and their technologies is electric aircraft and air taxis. Referred to as eVTOL (electric Vertical Take-Off and Landing), a class of manned and unmanned aircraft is being developed and certified for short-hop passenger transit from down-town ‘Verti-Ports’ to classic airports, aimed at improving the economics and reducing the noise footprint of current helicopter services. Urban air transport is undergoing significant change as organizations such as United Airlines, Delta, American Airlines and others plow money into electric aircraft and the development of manned and unmanned air axis.

    Archer Aviation is developing two such aircraft, with ‘Maker’ being the first cut flying test-bed, and ‘Midnight’ its so called ‘first production version.’ The vehicle design is similar in that they both have wings and are powered by six lift propellers and six tilting props that rotate vertically to lift for take-off and landing, then transition to horizontal for forward flight.

    In the past, Archer has been somewhat secretive about its air-taxi program, but with the introduction of Midnight on Nov. 17, and with Maker achieving transition from hover to forward flight on Nov. 20, they released some useful information. Lift to forward transition is a big step for eVTOL, with the potential for a major set-back, almost like an irrecoverable stall for a fixed wing aircraft.

    There are six battery ‘packs’ mounted in the wing near the engines – batteries, engines and FAA certification are key focal areas in their program, with fault tolerance and endurance being key considerations. An existing lithium battery has been selected following extensive testing, with a design objective of 10,000 average 20 mile trips, each trip with a 10 minute recharge cycle.  Two similar electric motor types are used, with 95% commonality, and flight can allegedly be maintained through one complete engine or propeller failure. Each engine has redundant elements allowing one side to fail while still maintaining full operation. All these redundancies support the Archer plan for FAA certification which has now progressed through ‘Certification Basis’ and ‘Conceptual Design’ to ‘Preliminary Design’. There are many steps still to complete, with certification not anticipated until at least the second half of 2024.

    Meanwhile, Joby Aviation has been making significant progress with its flying prototype and pre-production aircraft, with the objective of developing a flying rideshare platform. With space for four passengers and a pilot, the Joby aircraft is smaller than the Archer vehicle, however smaller size means less weight and complexity and requires fewer lift props. The Joby vehicle has six large props that all transition from vertical for take-off and landing to horizontal for full forward flight.

    Joby developed its own lithium-iron batteries and dual redundant electric motors and while developing flying prototype and pre-production aircraft, has also focused on teaming with key industrial partners who are assisted in key areas:

    • NASA has undertaken a study with Joby on 5 potential route configurations at Dallas/Fort-Worth airport for eVTOL traffic.
    • The US Department of Defence has provided flight range and facilities to enable airborne testing of the Joby prototypes. This contract has just been modified so that US Marine Corps personnel may flight test Joby’s eVTOL to evaluate DoD use-cases for the aircraft.
    • The company ‘Uber Elevate’ was purchased by Joby and is now integrated as the future provider of trip access for customers.
    • Toyota has not only invested in Joby, but is providing essential production facility knowledge and guidance as Joby begins its initial build out of volume manufacturing.
    • Delta has invested an initial $60 million, which could increase to $200 million provided progress towards certification and service entry meets certain milestones

    Other eVTOL notable companies entering this market include Jaunt Air Mobility in Dallas, Texas; Velocopter in Bruschal, Germany; Lilium in Munich, Germany; Kittyhawk in California; Wisk in California and New Zealand; Airbus in Toulouse, France; Ehang in Guangzhow, China; Vertical Aerospace in Bristol, England; Urban Aeronautics in Tel Aviv, Israel; and Eve Mobility in Melbourne Florida.

    So, just a small taste of two of many eVTOL hopefuls – but two with the backing of mainline commercial airlines – who knows who will actually make it through the arduous and expensive aviation certification process before the cash runs out? However, there are many significant investors who are currently standing by their selected hopefuls and others continue to jump in – let’s hope that by 2025 we’ll begin to see home-airport air-taxi services underway.

  • US Air Force invests in flying cars

    US Air Force invests in flying cars

    Are ‘”flying cars” unmanned aerial vehicles, manned aircraft, electric aircraft or just regular aircraft? Or perhaps a mix of all of these? Flying cars raise so much interest because of their potential to fulfill the space-age Jetsons promise, with the regular family parking one at their house, then using it to go to work, go grocery shopping and take the kids to school — all the things we do today in cars on roads.

    The U.S. Air Force recognized that flying cars could also revolutionize how it operates, and in 2020 started putting effort and cash into promising commercial flying-car ventures. Since then, the Air Force has begun to make progress. Its AFWERX Agility Prime program has helped four companies — Kitty Hawk Aero, Beta Technologies, Joby Aviation and Lift Aircraft — develop prototype commercial flying-cars and expand their capabilities.

    The Kitty Hawk Aero Heaviside

    Kitty Hawk Aero in Palo Alto, California, has been working on its electric vertical take-off and landing (eVtol) aircraft for several years and claims to have proven its tilting propeller concept through several hundred vertical take-off/landing to horizontal flight transitions.

    The aircraft — known as Heaviside — has just been granted airworthiness approval by the Agility Prime program, enabling Kitty Hawk to further participate in specialized trials funded by the Air Force.

    The majority of flight testing flown by Heaviside has been remote without on-board crew (one or two pilots). This has enabled Kitty Hawk to expand the flight envelope without risking lives. For instance, you might assume those initial vertical to horizontal transitions could have carried a degree of risk, even though those switches in flight mode are now considered virtually risk free.

    Nevertheless, the aircraft is also equipped with an on-board parachute recovery system that has been demonstrated to gently lower the aircraft to the ground in the event of a complete electrical failure. The design has minimized weight, even though the aircraft carries sufficient battery power to provide a range of more than 100 miles. A speed of up to 180 mph has been achieved.

    The Beta Technologies Alia

    Another AFWERX participant in the Agility Prime project is also well along in its flight test program. Beta Technologies has been flying its Alia prototypes on routes of more than 100 miles and pushing velocities of 150 mph.

    Alia is large — it’s in the 7,000-pound aircraft category with a 50-foot wingspan. Alia is designed to carry six people over 250-mile routes, with a cargo capacity of 1,500 pounds. It is powered by on-board lithium-ion batteries. The Air Force expressed serious interest in the design and flight-test planning phase before Alia became airborne. The craft has since proven it is capable of safe, reliable flight over routes such as Plattsburg to New York. The Federal Aviation Administration has authorized such flights ahead of time, but Beta also just received additional airworthiness authorization from the Agility Prime office to enable further trials.

    The Air Force clearly has great faith in Beta Technologies. The company received an even greater boost to its Beta eVtol program from the commercial sector. BLADE Urban Air Mobility has already ordered 20 of these electric aircraft, and UPS has also ordered 10, with the expectation that their order could grow to up to 150. UPS can clearly see the time and cost advantage of landing aircraft directly at its package-sorting facilities, then loading and vertically launching Alai onto delivery routes, either manned or autonomously as a cargo UAV. United Therapeutics, which is developing artificial organs for human implantation, is another key sponsor, presumably to find the shortest transit time to client hospitals.

    Amazon also may become involved following Beta’s recent successful $368 million funding round led by Fidelity and Amazon’s Climate Fund, giving the company stratospheric “unicorn” valuation of more than $1 billion. Maybe there could be Amazon package delivery service in Beta’s future.

    The Joby Aviation Craft

    Joby Aviation is another earlier participant in the U.S. Air Force’s Agility Prime program and was granted airworthiness authorization in 2020. Joby first flew a subscale prototype in 2015 and a full-size aircraft in 2017, with the objective of proving the viability of a tilt-rotor, four-passenger flying taxi/eVTOL aircraft.

    Joby’s story may be similar to the other companies developing electric flying cars, save that it has been doing this since 2009. Over time, Joby has won significant funding and support from key industry sponsors including Toyota, Uber, Elevate and Agility Prime. A study by Lufthansa in 2021 touted Joby as the leader in the eVtol competition.

    The FAA has agreed that Joby can proceed down a certification path applying regular general aviation part 23-64 rules, plus special conditions that include special attention for batteries and fly-by-wire controls. Joby is making good progress toward certification objectives, having already flown more than 1,000 times with different prototypes.

    With six tilt-rotors driven by electric motors, Joby’s yet-to-be-named four-passenger aircraft is capable of 200 mph with a +150-mile range, weighs 4,000 pounds and is apparently one of the quietest, measuring only 65 dBA at ~110 yards while hovering. A low noise profile is key to acceptance of these relatively low-altitude flying-cars as they buzz across densely populated areas — and all manufacturers have come up with low-noise-profile designs.

    The Lift Aircraft Hexa

    Lift Aircraft has taken a different path toward introducing flying-car technology into everyday use by borrowing more closely from existing drone capabilities. The company hopes acceptance will be quicker under its adopted FAA’s Powered Ultralight classification (FAR Part 103), which does not require a pilot’s license to fly.

    The Lift approach also intends to take so many precautions and use so much automation that anyone can fly its Hexa. Floats prevent sinking for forced landings on water; triplex flight-computers, GPS and IMUs add to the fail-safe design; and an automatic parachute release in the event of an in-flight incident deploys a “whole-aircraft air bag.” Along with 18 redundant electric-motor-driven propellers (only 12 are needed for a safe landing), these features add up to safety for the uninitiated.

    The single joystick control is simple to use and allows the unskilled to fly the drone-car safely. The system comes with extensive monitoring built in, so remote safety operators can intervene in extreme situations. Flight is currently only allowed in geo-referenced airspace defined by Lift. The vehicle has the capability to fly itself out of potentially dangerous situations and avoid mapped obstacle locations. Flight is semi-autonomous and take-off and landings are automated.

    Agility Prime joined with Lift in April 2020 to support the company’s safety testing, and in August 2020, funded expansion of the Hexa flight envelope. The Air Force has loaded a Hexa drone-car into a C-130 transport aircraft and flown it to another location to verify transportability for remote deployments. Lift has also won another contract from the Air Force for autonomous cargo retrieval based on a subset of the Hexa design elements.

    It is possible that many people will see Hexa in operation during a coming demonstration tour planned for major population centers across America – 15,000 people have apparently already signed up to fly Hexa when the tour gets underway, possibly later this year.

    Wrapping It Up

    So are these craft flying cars, or drones carrying people? It’s still hard to say definitively, but for sure many experts believe in the forecast of 160,000 flying taxi-cars by 2050, with airport shuttle and air-taxi markets reaching a market value of $500 billion. Certainly the Agility Prime program seems to have got it right and taken the necessary steps to ensure this technology gets out of its emerging, curio stage and out into a world eager to adopt it. If only we could accelerate the extremely lengthy civilian certification phase while still embedding increasing levels of safety. Perhaps the Air Force program can get us there quicker.
