AirShip VTOL UAV
AirShip VTOL UAV AirShip Air and Ground Transit The strategy calls for designing, building and ground-to-air testing a full scale prototype with a sturdy undercarriage for use on rough sites/terrain and tight and primitive landing zones of forward operating bases (FOBs).
130375688AirShip VTOL UAV In-Motor Ground Wheel Hubs After launch and reaching the desired altitude, the ATG VTOL UAV is capable of extending (transforming) its low aspect wings and rear V-Wing while partially retracting and shielding its ground transit wheels to reduce drag.
130402334AirShip VTOL UAV In-Motor Ground Wheels Extended Ground transit is accomplished by electric motors mounted in the wheels at each of the three by four configured wheel assemblies. This wheel hub motor combination is an electric motor that is incorporated into a hub of the aircraft?s ground wheels and using drive-by-wire controls, allows the operator to drive the air/vehicle in a three or four wheel configuration for ground transit.
130402335AirShip VTOL UAV Transformed at Rest Landing and taking off from short, narrow, unimproved sites is the most difficult requirement to meet, but the ATG VTOL compares favorably to comparative aircraft, since the ATG VTOL will be able to take off and land equal to an area of its transformed footprint shown here.

130442131AirShip VTOL UAV Safety and Passenger Configuration To improve ATG VTOL UAV over other competitor aircraft, a number of survivability characteristics are embedded in the design and development of the aircraft to reduce damage and human injury. For the pilotless, but passenger version of the extended mission capability, protecting the transport troops or injured during rescue flights is a prime imperative. To improve human safety, we integrated crash-protection technology into seats and restraint systems with off-the-shelf technology. Second, reducing the risk of fire and explosions was essential to reducing injury and fatality rates. Installing fire-resistant fuel lines, fuel tanks, and the use of fire-retardant fluids is designed substantively to reduce this cause of mishap failures.
130443571AirShip VTOL UAV Hybrid Electric Powertrain The aircraft?s motors, Hybrid Fuel-to-Electric powertrain and ducted fan rotor assemblies use advanced power plants, specifically designed for present and future relevant VTOL UAV missions. Emphasis has been placed on excess power available at high gross weight to medium density altitude, reliability, and fuel consumption management. High performance from the aircraft?s powertrain and ducted fans set the design criteria. The design goal is to architect and design the right powertrain and propulsion systems first and then develop the VTOL aircraft around it, as has been done with tactical aircraft development.
130443576AirShip VTOL In-Flight The aircraft can hover while being acoustically quiet and requires no expensive and perishable piloting skills.
130445297AirShip VTOL Airframe Where the fuselage airframe curves intersect, hollow joints allow pieces to be fitted together. This technique creates an extremely stable and rigid internal cargo-payload compartment cell, improving safety. Composites, aluminum and titanium have a high strength-to-weight ratio, but they are inherently less stiff than steel. Hence, in some of the aircraft?s structure larger cross sections of these materials are required to duplicate the stiffness of a steel structure. This tradeoff undermines some minor weight savings. The ATG VTOL UAV?s airframe ends up about 50 percent lighter than alternatives. The composite, aluminum and titanium can be easily extruded - pushed through a relatively inexpensive die to form lengthy surfaces with complex aerodynamic cross sections.

130450472AirShip VTOL UAV Flight 3-Wheel Drive Configuration After launch and reaching the desired altitude, the ATG VTOL UAV is capable of extending (transforming) its low aspect wings and rear V-Wing while partially retracting and shielding its ground transit wheels to reduce drag and move from a 4-wheel drive configuration to a 3-wheel drive configuration.
130451304AirShip VTOL UAV Ground 4-Wheel Drive Configuraton Ground transit is accomplished by electric motors mounted in the wheels at each of the three by four configured wheel assemblies. This wheel hub motor combination is an electric motor that is incorporated into a hub of the aircraft?s ground wheels and using drive-by-wire controls, allows the operator to drive the air/vehicle in a three or four wheel configuration for ground transit.
130451303AirShip VTOL UAV Hover Capability The aircraft?s three turbine assemblies supporting twin counter rotating ducted fan rotors (two laterals and one rear) provides the configuration to ensure the air/vehicle?s hover stability. The AirShipTG VTOL UAV is able to hover by aerodynamic means. The aircraft?s ducted fan rotors rotate, and as it does so, generates an aerodynamic propulsive lift force. The air/vehicle pulls itself upward to a hover position because of the aerodynamic force acting on its rotors as they slice through and displace air. This image illustrates the AirShipTG VTOL UAV ?pushing against the ground," as it were, and the red streamlines indicate the high-velocity air exhaust exiting through all three ducted fan rotors producing the thrust needed to keep the aircraft airborne and into a hover position.

137275724AirShip VTOL UAV Aerial and Anterior Component Views The exterior fuselage aerodynamic front to rear quarter panels, slide forward doors, low aspect wings, rear V-Wing tail and anterior panels are constructed from ceramic ballistics protected composites. Smaller external components and the overall airframe is constructed of treated cast aluminum or titanium that is impervious to rust and corrosion and also staunchly resistant to dings and dents. Expectations are for the aircraft exterior to hold up against corrosion for an estimated 25 years. The aircraft aerodynamic front-end, flexible outer fuselage are designed and manufactured to absorb light impacts. The AirShip VTOL UAV basic structure is formed from a combination of stamped, extruded and cast composites with much of it bonded by high-strength adhesives, along with conventional welds.

AirShip VTOL UAV Transformer specifications call for a 1,000 pound payload cargo bay, a top speed of 300 mph (260 knots nautical miles per hour), a significant nautical range , and an altitude ceiling of 10,000 feet. The aircraft is designed for reliability, internal and external sensitive acoustics, and an environmentally sensitivity due to non-polluting benefits of the hybrid electric power plant.
137286394Air Accelerator Powertrain Alternative As part of continuous measureable improvement, AirShipTG continues to research and develop alternative industrial strength rotorless-based ducted air foil technology. The goal is to augment the AirShip VTOL UAV Transformer with alternative propulsion systems that are quieter, less complex, reduced weight and has efficient power to thrust for the air/vehicle. In a sense, it allows for the continuing evolution of the aircraft?s future. AirShipTG is currently conducting research on methodologies for attenuation of sound propagation and acoustic impacts of liquid fuel engines with turbine rotor blades. This research has explored the feasibility of a quietly operating High Speed Continuous Helical Air Accelerator Ducted Fan Turbine alternative. This turbine would simultaneously accelerate the air mass through the turbine and compress the air for greater lift efficiency.
