As reported in many personal accounts by the pilots in their memoirs, the speed at which the aircraft would actually stall was 24 miles per hour (39 km/h). Either speed making it the slowest aircraft used in WW2 and possibly the slowest conventional warplane of all time. [6] The Antonov An-2 had no published stall speed. At low speeds its ...
A fixed-wing aircraft can be made to stall in any pitch attitude or bank angle or at any airspeed but deliberate stalling is commonly practiced by reducing the speed to the unaccelerated stall speed, at a safe altitude. Unaccelerated (1g) stall speed varies on different fixed-wing aircraft and is represented by colour codes on the airspeed ...
Retreating blade stall is a hazardous flight condition in helicopters and other rotary wing aircraft, where the retreating rotor blade has a lower relative blade speed, combined with an increased angle of attack, causing a stall and loss of lift. Retreating blade stall is the primary limiting factor of a helicopter's never exceed speed, V NE. [1]
The minimum such speed is the stall speed, or V SO. The indicated airspeed at which a fixed-wing aircraft stalls varies with the weight of the aircraft but does not vary significantly with altitude. At speeds close to the stall speed the aircraft's wings are at a high angle of attack. At higher altitudes, the air density is lower than at sea level.
A leading-edge slot is a fixed aerodynamic feature of the wing of some aircraft to reduce the stall speed and promote good low-speed handling qualities. A leading-edge slot is a spanwise gap in each wing, allowing air to flow from below the wing to its upper surface.
Compared to the similar RV-7, the RV-9 has a wing of increased span and higher aspect ratio using a Roncz airfoil. The RV-9 has a low stall speed, comparable to the Cessna 150, and docile handling suitable for low-time pilots. The cruise speed is a very respectable 167 mph (269 km/h) TAS even with the 118 hp (88 kW) engine. [6]
For efficient Cruise flight, the BlackFly cants the wings and propellers to an optimal angle of attack. The forward wing has a slightly lower angle of attack to aid stall recovery. At low speeds, the forward wing will stall first, causing the nose to fall, increasing air speed and automatically exiting a stall. [6] [11]
The Edgley EA-7 Optica is a British light aircraft designed for low-speed observation work, and intended as a low-cost alternative to helicopters.The Optica has a loiter speed of 130 km/h (70 kn; 81 mph) and a stall speed of 108 km/h (58 kn; 67 mph).
