The Corvo Precision Payload Delivery System (PPDS) is a small aerial drone originally intended for logistics, weighs 2.4 kg (5.3 lb) empty, and deliveries payloads of up to 3 kilograms (6.6 lb). [1] The airframe is made of waxed foamcore (foamboard) and the drone is supplied as a self-assembly flatpack, complete with a tablet-PC control centre ...
A toroidal propeller is a type of propeller that is ring-shaped with each blade forming a closed loop. The propellers are significantly quieter at audible frequency ranges, between 20 Hz and 20 kHz, while generating comparable thrust to traditional propellers. In practice, toroidal propellers reduce noise pollution in both aviation and maritime ...
The CH-802 has a cylindrical fuselage with propulsion being provided by a two-blade propeller driven by a tractor brushless electric motor atop the fuselage. [37] [38] The CH-803 is mainly intended for reconnaissance and surveillance missions. [35] The CH-802 program began in 2007 and was completed in 2008. Specifications: [39] [40] Wingspan (m): 3
Drones can be used privately and commercially. In any case, the drone must be controlled using a visual line of sight between the pilot and their vehicle. [16] Licenses. A1/A3: Required for drones of 250 grams (8.8 oz) or more, a free online exam with 40 multiple-choice questions after registration, and confirming the pilot's identity. After ...
Using the standard gas engine and pusher propeller, the AQ-400 has a cruise speed of 144 km/h (89 mph), a top speed of 200 km/h, endurance of 6.5 hours, and a strike range of 750 km; depending on the engine option, range could be increased as far as 900 km (560 mi), or payload increased to 70 kg (150 lb) at a reduced range.

Other terms include ducted propeller or shrouded propeller. [1] When used in vertical takeoff and landing applications it is also known as a shrouded rotor. [2] Ducted fans are used for propulsion or direct lift in many types of vehicle including airplanes, airships, hovercraft, and powered lift VTOL aircraft. The high-bypass turbofan engines ...
The Lockheed Martin Stalker was created in 2006 by the same Skunk Works team responsible for the Desert Hawk.It was hand launched and belly landed, had a quiet electric motor and propeller, and carried a detachable camera payload.
