  • A New UAV Architecture for Urban & Maritime Environments VTOL Technologies Ltd – Delivering unique, high-performance Vertical Take-off and Landing technologies for fixed-wing UAV’s. Cheaper & safer alternatives to helicopter & tilt-rotor UAV’s delivering high performance for urban, mountainous & maritime operations.
  • An Introduction [1]…
    • A small British company VTOL Technologies, formed as a direct result of the fall-out, following the events of September 11th 2001, has been quietly working over the past 8 years to develop a revolutionary VTOL UAV concept. Detailed research and analysis into all known VTOL aircraft architectures, coupled with extensive systems-engineering expertise, has culminated in a unique VTOL UAV concept combining a flying wing with four thrust-vectoring propulsion units, delivering a high payload fraction in a hot-swappable payload bay located under the wing.
    • The company has just completed a detailed concept study for the UK MoD clearly establishing the benefits of this exciting design. The concept is a superb piece of minimal ‘systems-engineering’ based design, eliminating redundant aircraft features that add weight, overcomplicate flight control, increase drag and reduce endurance. In its place is a smaller, lighter, quieter, flexible and scaleable architecture.
    • Some of the advanced features include almost instantaneous stall recovery, gust insensitivity, reverse thrust to enable the platform to be ‘sucked down’ onto the deck of a ship pitching in heavy seas and minimum power to rotate the thrust-vectoring propulsion units. Even loitering into wind, keeping the vehicle airborne with minimal power, just like sea birds, is also a feature.
  • An Introduction [2]…
    • In the event of power failure in one or two of the propulsion units, the vehicle can still remain airborne and fly at close to its cruising speed, whilst total propulsion unit failure poses fewer risks than for rotary-wing craft such as helicopters by flying with a shallow glide-angle, rather than at best the rotary-wing craft descending to the ground with its rotor-blades auto gyrating.
    • This unique patent-pending design has 3 to 4 times the endurance of current VTOL UAV’s carrying an equivalent power source and payload but delivering significantly faster cruise speeds, whilst the same comparisons with current fixed-wing UAV’s demonstrate more than twice the endurance, but with the added advantages of VTOL, high manoeuvrability, low-power loiter and a continuous speed range, which enable this platform to readily operate in urban canyons, still a huge challenge for current UAV systems. The thrust-vectoring propulsion unit design enables the UAV to be launched and recovered from moving vehicles or ships without the need for ancillary equipment.
    • With advances in specific green fuel-cell technologies, these endurance ratios could be quadrupled within the next couple of years, delivering the much needed very long endurance figures, not possible with today’s small, low-altitude UAV’s. If development can now be accelerated, we might even see this platform operating in Afghanistan, helping to save soldiers lives, operating from ships both large and small to assist in counter piracy operations and being used for the London 2012 Olympics to enhance security.
  • Why Design Yet Another VTOL UAV Architecture?
    • Step 1 – Why the need for a specific urban, (mountainous) & maritime environment UAV?
    • Step 2 - What is the business case for a new UAV architecture for urban, (mountainous) & maritime environments?
    • Step 3 - What are the technical barriers to successful operation in urban, (mountainous) & maritime environments?
    • Step 4 - What are the operational & commercial advantages of such an architecture?
    • Step 5 - How to find out more regarding partnership and business opportunities?
  • Why a New UAV Architecture for Urban & Maritime Environments?
    • Our world demographics are changing rapidly.
    • Over 70% of European & North American populations live in urban environments today.
    • Over 50% of the World’s population lives in an urban environment today.
    • Because our urban environments are congested (vehicles & people), we have to ‘go to the air’ for rapid assessment (surveillance & reconnaissance) of situations/incidents on the ground.
  • World Population Demographics – Our Changing Planet…
    • Since 2008, for the first time, half the world’s population is now living in towns and cities. By 2030, the urban population will reach 5 billion — 60 per cent of the world’s population (see graph). Nearly all population growth will be in the cities of developing countries, whose population will double to nearly 4 billion by 2030 — about the size of the developing world’s total population in 1990.
    With urban environment congestion, UAVs are going to be a valuable aerial resource for our First Responder services. Critical issues are rapid deployment & recovery, safety, manoeuvrability, ease of use, endurance, low noise signature, etc.
  • Urban & Maritime Environments - The Technical Challenges
    • Flying at low altitude in urban, mountainous and maritime environments is technically extremely demanding. Current UAV architectures have challenges addressing the following environmental conditions:
    • Gusting
      • Winds around buildings and ships can gust at up to 20kts. Remaining stable in the air, particularly at low altitude & low speed is exceptionally difficult to achieve unless you have an airframe architecture which has been specifically designed to handle these challenging conditions. Helicopters have exposed rotors, which make them susceptible to adverse aerodynamic effects (flipping over when close to land, buildings, etc).
    • Safety
      • Operating in environments where people are around requires a safe UAV platform. Exposed rotors can be a hazard, as can the inability to glide if power is lost to the rotors. High power in the hover and at low speed is noisy and can distract people on the ground.
    • Deployment & Recovery
      • Operating in urban environments or from ships, means that launch & recovery space is at a premium. VTOL provides for the ability to operate from an extremely small footprint. However, the helicopter footprint is still relatively large as a result of their rotors.
    • Endurance
      • High endurance is essential for both urban and maritime operations. Today’s small fixed wing and rotorcraft UAV’s have limited endurance and low efficiency, limiting their time in the air and the distances they are able to cover.
    • The very low (<1000’ and low altitude market segments represent 97% of the market share by number of units deployed.
    • This segment of 97% of total number of units deployed at these altitudes represents over 80% of UAV deployed in urban, mountainous and maritime environments.

  • No Other UAV Architecture Can Respond as Effectively to Gusts… Almost instantaneous stall recovery is also achievable from this specialised flying-wing aerofoil section. Additionally, rapid pitch correction can also be achieved, through variation of the front and rear fan thrust levels, given the available moment arm. With only +/- 5 o of port/starboard fan rotation at any angle of fan inclination (i.e. across the entire UAS speed range) and with zero yawing moment, a 50% increase in roll moment can be achieved, thus providing the ability to withstand exceptionally strong gusts, unlike any other known UAS platform. This UAS can also “hover on the wing”, extending endurance in high ‘power-demand’ situations.
