eZELOS 300 Air Taxi (defunct)
Swiss Aéropôle, Payerne, Switzerland www.uasystems.com
Founded in 1995, UASystems SA (Uncrewed Aircraft Systems SA) is a Switzerland based company manufacturing unmanned multicopter drones, mission controllers, ultralight engines, mechanical subsystems, piloted, optionally piloted rotorcraft and more. They are currently working on their own full scale hybrid-electric vertical takeoff and landing (VTOL) passenger and air cargo aircraft for advanced aerial mobility (AAM). The company's slogan is Pursuit of the Future. The company is currently seeking investors, please contact the company using their website. (Image credit: UASystems SA)
The company's hybrid-electric VTOL aircraft can be flown in full electric mode, piston engine mode (direct drive) or in hybrid-electric mode. The company states that having three power sources on-board provides the maximum amount of flexibility, safety, range and flight time for their class of aircraft. By having two petroleum fueled engines, if one fails, the other engine can land the aircraft safely. If all power sources fail, the aircraft can autorotate to safety.
The company is developing a hybrid-electric free piston linear generator named the Beetron generator which can use natural gas, biogas, heating oil, gasoline, ethanol, hydrogen and solar synthesis gas to create electricity to power all electric motors and the aircraft's electrical systems. The engine is estimated to last for 20,000 hours. Their engine uses or has less parts, friction, weight, maintenance, fuel consumption, emissions and operational costs than traditional petroleum-only engines. The engine is used in conjunction with battery packs.
eZELOS 300 Air Taxi all-electric or hybrid-electric passenger defunct concept design helicopter
The eZELOS 300 Air Taxi is an all-electric or hybrid-electric defunct concept design helicopter and has one pilot and carries two passengers. The aircraft has a maximum payload 300 kg (661 lb). In case of a power loss, the helicopter can land using autorotation. The company also has redundancy built into the helicopter providing an additional margin of safety which will be used for the future production aircraft.
Each main rotorblade has three blades and are in a coaxial configuration, meaning that one main rotorblade is stacked on top of the other. The main rotorblades turn in opposite directions to counteract torque. It is also known that helicopters with coaxial rotorblades typically have a higher maximum payload, than helicopters in the same class with only one main rotorblade.
The helicopter also uses a pusher propeller located in the very rear of the helicopter in the tail boom. The tail boom has a horizontal stabilizer at the end of the tail boom and there is a wingtip fence on the end of each horizontal stabilizer. The aircraft also has tricycle wheeled landing gear. The front landing gear might be retractable and the rear two wheels are fixed landing gear. The rear landing gear has a wing-shaped structure providing additional lift during forward flight.
