Potentially unlimited range for UAVs and flying cars:

Another barrier to the commercial development of UAVs and (Unmanned Aerial Vehicles) and flying cars has been breached with the announcement of the Neva Aerospace SpaceBridge™ concept.

SpaceBridge networks for "Charging and re-provisioning station for electric and hybrid unmanned aerial vehicles" (patent protected), would provide the power platform for wide area operations of aerial electric vehicles, manned (flying cars) or unmanned (drones).

Neva Aerospace has developed underlying propulsion technology that will allow for longer distance, heavier-duty electrical VTOL craft and it already markets modular turbo-drones™ and OEM turbo-fans optimised for VTOL and STOL. Now it has also addressed the key challenge of flight duration with the technologically-viable idea of SpaceBridge recharging stations.

The core concept:

SpaceBridge™ SpaceBridge is conceived as an infrastructure network of specialised docking stations catering for manned and unmanned electric aerial vehicles, and will serve any make of aerial vehicle. The concept is patent protected.

Stations will be deployed in a variety of locations such as cities or along trajectories connecting cities. Unmanned (UAV) and manned (MAV) aerial vehicles, including Neva’s existing Eole modular drones or future AirQuadOne and AirCab4, will be able to land automatically on Spacebridge docking stations, where battery packs are rapidly swapped before the aircraft continues its journey.

Current battery technology limits the practical flight time of, for instance, a compact 4-person all-electric VTOL aerial vehicle to around twenty minutes with reserves. Whilst this flight time can certainly be improved by making the vehicle larger and lighter, engineers ae well aware that performance in terms of speed, flight agility, flight stability and practicality suffers greatly.

The SpaceBridge concept solves this problem by allowing an aircraft to land automatically at intermediate locations along its journey path; at these locations (the SpaceBridge stations) the vehicle’s battery would be changed automatically (typically within thirty seconds to one minute) before resuming its journey. If the practical range of a given all electric air-taxi is around 30kms with reserves, laying out six SpaceBridge stations at a 30km spacing enables you cheaply, rapidly and easily to connect two cities 150kms apart. Spacebridge stations may also be scattered around a city forming the basis for a clean efficient aerial transport network.

SpaceBridge Hubs:

Hubs can be integrated into current airports or built on city rooftops. Each hub may provide multiple docking bays, air-bridges and lounges where passengers can embark and disembark. More simple Spacebridge stations (where passengers do not alight, such as would be used to assure intercity transport) consist of a single docking station typically mounted on a tall concrete pylon.

Up until now however, the great problem with suitable electric vehicles has been the intrinsically small flight time. SpaceBridge solves this issue both for inter-city and intra-city transport for countries and municipalities cautious of their resources and environmental impacts.

Powering smaller drones:

Neva also envisages the sustainable SpaceBridge concept being applied to many other fields. For example coastal or border surveillance and rescue is often required over great distances and yet even small electric drones cannot fly these distances. Low-cost SpaceBridge recharging stations, coupled for example to solar panels, could solve this problem. Other major applications that the company sees are in agriculture and parcel delivery.

Definition: An axiom is a statement that everyone believes is true, such as "supply equals demand" or "the only constant is change." Mathematicians use axiom to refer to established proofs.

In 2009 Neva Aerospace co-founder and Chief Science Officer Prf. Brotherton-Ratcliffe defined the axioms of 3D Distributed Thrust for Aeronautic Levitation and Propulsion. They formed the basis of the original patent for Neva Aerospace technology, and their definition was the starting gun for a new era of aeronautical design.

We do not believe they can be challenged, or that any solution that does not adhere to them will be safe, scalable, viable or able to satisfy regulators.

The Brotherton-Ratcliffe Axioms:

  • The reactivity of turbine thrust systems depends on the inner mechanical momentum of the turbine and consequently an efficient Levitation system requires:
    • a plurality of high-average-power high-static-thrust low-modulation-frequency thrust systems to compensate for most of the gravity, and
    • a plurality of low-average-power high-modulation-frequency thrust systems to compensate for force transients.
  • Thrust systems should be dispersed around the vehicle on a surface whose normal is the gravity axis in order to create a levitating support thrust which is more-or-less evenly distributed over said surface, thus reducing thrust density and conferring a fundamental redundancy of operation among the plurality of thrust systems.
  • In order to confer 3D flight stability, a subset of the thrust systems described above should be replaced with intrinsically 3D thrust systems, said systems being capable of thrust in additionally two mutually orthogonal directions to the gravity axis.
  • For high-speed efficient linear flight, an aerofoil should be incorporated in the design and high dynamic thrust turbines used for linear propulsion.

Our patented "3D Distributed Propulsion" technology is still the only viable available solution for flying, hovering and transition from VTOL to linear flight, with useful payloads.

Other than our axioms for 3D Distributed Propulsion and standard helicopter and airplane designs, we believe there is no real scalability. It comes down to physics and aerodynamics.

See the original Patent: Electric VTOL Aircraft using Electric Ducted Fans.

AirQuadOne, the first “flying quad”, is a fully-electrical vehicle expected to weigh around 500 kg and carry payloads of up to 100kg. It is expected to be certified under Light Aircraft certification within the USA(FAA) and EU (EASA).

FLIGHT TIMES:
20 to 30 minutes
LINEAR FLIGHT SPEED:
up to 80 Km/h
ALTITUDES:
up to 3 000 ft.

The 100+kg battery pack is anticipated to be compatible with electric cars’ recharging stations, via direct wire connection, induction or a battery pack switch.

Its unmanned version should be able to lift payload up to 100kg, and replace cranes and helicopters or emergency cars.

Neva’s patented 3D distributed thrust technology

Neva is now working with regulators and pilots to seek light aircraft certification within the USA(FAA) and EU (EASA) for the first users. Neva AirQuadOne will have 24/7 traffic management support when flying, with an emergency satcom connection.

Neva Aerospace is committed to developing sustainable solutions and AirQuadOne will be manufactured using recycled carbon.

Applications:

Underlying technology:

AirQuadOne’s power and endurance are made possible by the technology Neva Aerospace has conceived and developed. Neva’s static thrust electric turbofans (ETFs) will provide for manned and unmanned vehicles with payload capabilities up to 100Kg.

A hybrid version of AirQuadOne will,we anticipate, be able to provide flight time around 60 minutes, based on current battery technology.

Our team continues research & development in the UK and in Germany to achieve the expected specifications.

Neva’s static thrust and semi-dynamic electric turbofans (ETFs) are designed to optimise the Vertical Take-Off and Landing (VTOL) that is a pre-requisite for the use of UAVs and personal aircraft in crowded industrial and urban skies. Unlike a standard electric ducted fan (EDF), a Neva electric turbofan (ETF) has a specifically calculated shaped inner shroud.

Applications:

  • Extreme Sports & Leisure
  • In-city parcel transportation
  • Robotic maintenance
  • Active defence
  • Heavy static heavy lift

Over the years we have built many prototypes to test various parameters and prove our concepts.

Neva Alpha

First was Alpha, and its maiden tethered flight in the lab was an exciting milestone for us: we knew for sure that we were on the right track.

To put the achievement in context: a typical camera drone has only four propellers and is unlikely to weigh more than 3kg, yet our original Alpha laboratory prototype had 17 turbines and weighed in at 42kg!

After we saw Alpha fly, we were confident that our distributed thrust technology is the future of commercial unmanned aviation.

Alpha used electric ducted fans (EDFs) originally designed for planes. These EDFs are not efficient for VTOL operation, and so we have gone on to design our own series of turbines optimised for static thrust. The Athena series is now commercially available.

Core concepts

The success of Alpha led us to progress further our concepts for logistics and maintenance UAVs. The technology is explained in this video which shows how we see the future.

Fast forward

With the availability of our own, static thrust Athena fans – a world first – we are now able to accelerate our plans. We have built a test platform to help progress our technology. We call it Wohler-b.

Wohler-b is also the precursor of our range of Eole OEM multi-turbine modules that will soon be available. The Eole range will be prettier than Wohler – but Wohler will always have a special place in our hearts. It's successful first test flight in January 2017 was another key milestone for Neva Aerospace.

Another key milestone – the successful Wohler-b test flight.
