where is propulsive efficiency (typically 0.65 for wooden propellers, 0.75 metal fixed pitch and up to 0.85 for constant-speed propellers), hp is the engine's shaft horsepower, and is true airspeed in feet per second, weight is in lbs. The metric formula is:
The Helicron is an open-wheel car that used a propeller as its drive. The Helicron was abandoned in the late 1930s, but was restored after its barn find in 2000. [1] In the same year, the car was permitted by the French government to drive on the French roads. [2] The car currently resides in the Lane Motor Museum and is on display, as a ...
Among the designs he tried was the Oehmichen No. 2, which employed four two-blade rotors and eight propellers, all driven by a single engine. The angle of the rotor blades could be varied by warping. Five of the propellers, spinning in the horizontal plane, stabilized the machine laterally. Another propeller was mounted at the nose for steering.
Its 190-inch propeller diameter (4.7-metre) was smaller than the NK-12's 220–240 in (5.6–6.2 m) diameter, but it produced a power output of 21,007 hp (15,665 kW), delivering a takeoff thrust of 40,000 pounds-force (177 kilonewtons). [12] Even more powerful was the NK-62, which was in development throughout most of the decade.

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 H502E, also marketed as the "H502E X4 DESIRE CAM" is a smaller version of the H501S quadcopter. Uses brushed motors, has 12 minutes' flight time, 7.4V (2S) 610 mAh Li-Po battery, GPS Positioning, altitude hold, 720P High Definition Camera and return to home. Includes the standard TX H907A remote, extra props, USB charger and a tiny screwdriver.
A brushless, geared inrunner motor in a quadcopter. The term inrunner refers to an electric motor where the rotor (runner) is inside the stator. The term is in particular used for brushless motors to differentiate them from outrunners that have their rotor outside the stator. The vast majority of electric motors are inrunners.
