Propeller slipstream reduces the stall speed by energizing the flow over the wings. [26]: 61 Speed definitions vary and include: V S: Stall speed: the speed at which the airplane exhibits those qualities accepted as defining the stall. [26]: 8 V S0: The stall speed or minimum steady flight speed in landing configuration. [27]

The RV-9 was designed from the start as a two-place, side-by-side, touring aircraft and as such it forgoes the aerobatic capabilities and the lighter handling for more stability and economy. As such the design horsepower is 118–160 and the prototype was flown with a Lycoming O-235 powerplant of 118 hp (88 kW) as a proof-of-concept for the ...
The British Auster WW2 reconnaissance aircraft had a placarded stall speed of 24 knots (44 km/h; 28 mph), [5] but that was merely the speed at which its control surfaces lost authority. 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).
Stall speed or minimum steady flight speed for which the aircraft is still controllable in a specific configuration. [7] [8] V S R: Reference stall speed. [7] V S R 0: Reference stall speed in landing configuration. [7] V S R 1: Reference stall speed in a specific configuration. [7] V SW: Speed at which the stall warning will occur. [7] V TOSS
The plans consists of 29 sheets of blueprints, a 50-page construction manual and a 20-page flight manual, available in both English and German. The plans cost €350 and a completed aircraft is estimated to cost €8000. [2] [4] The aircraft has very benign stall characteristics, resulting in a controllable slow speed mush condition. [2]
Coffin corner (also known as the aerodynamic ceiling [1] or Q corner) is the region of flight where a fast but subsonic fixed-wing aircraft's stall speed is near the critical Mach number, making it very difficult to keep an airplane in stable flight. Because the stall speed is the minimum speed required to maintain level flight, any reduction ...
The ASK 21 was designed by Rudolf Kaiser to replace the popular ASK 13, providing a modern two-seat aircraft bridging the gap between initial training and single-seat performance flying. The ASK 21 is the first full-GRP two-seater produced by Schleicher , flying for the first time in February 1979.
