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 ...
Steady flight, unaccelerated flight, or equilibrium flight is a special case in flight dynamics where the aircraft's linear and angular velocity are constant in a body-fixed reference frame. [1] Basic aircraft maneuvers such as level flight, climbs and descents, and coordinated turns can be modeled as steady flight maneuvers. [ 2 ]
Stall speed or minimum steady flight speed for which the aircraft is still controllable. [7] [8] [9] V S 0: Stall speed or minimum flight speed in landing configuration. [7] [8] [9] V S 1: 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 ...
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, at a given gross weight and G-force loading. In this region of flight, it is very difficult to keep an airplane in stable flight.
The current OSU Airport began in 1943 as a flight training facility for military and civilian pilots, operated by the OSU School of Aviation. [6] The airport was used as a research location for crop dusting aircraft in the 1940s. A Piper J-3 Cub was used for testing until it crashed in 1957 and the project was halted. [5]
To unfamiliar flight crew, the activation of the stick pusher can feel particularly abrupt, vigorous and alarming, but this is an intended and normal part of its functionality to ensure it takes effect before a serious stall sets in. [7] Furthermore, aircraft designers who install stick pushers recognise that there is the risk that the device ...
From about 1937, the London-based Willoughby Delta Company was considering the construction of a flying wing airliner. The novelty of the design became apparent early in 1939: the Delta 9 was to be a tri-motor monoplane with a span of over 100 ft (30 m) with a thick and wide chord centre section, outboard of which the wing was thicker and much greater in chord, in part forming one of a pair of ...
Forces of flight on a powered aircraft in unaccelerated level flight. Understanding the motion of air around an object (often called a flow field) enables the calculation of forces and moments acting on the object. In many aerodynamics problems, the forces of interest are the fundamental forces of flight: lift, drag, thrust, and weight. Of ...
