Compressibility — This article is about thermodynamics and fluid mechanics. For other uses, see Compression (disambiguation). Incompressibility redirects here. For the property of vector fields, see Solenoidal vector field. Thermodynamics … Wikipedia
compressibility — A general term covering the effects resulting from the fact that the density of air, and gases in general, varies with pressure and hence with wind speed. The effects become apparent in the changes in the values of lift and drag coefficients of a … Aviation dictionary
compressibility error — An error in the airspeed indicator, which presumes that the air is incompressible. However, air is compressible and the higher the speed, the higher pressure it will indicate. An ASI (airspeed indicator) overreads because of the compressibility… … Aviation dictionary
compressibility drag — A parasite drag caused by the extraordinary compression of air ahead of an aircraft at high speeds. An aircraft not designed for sonic flights is especially prone to encounter this phenomenon as it approaches the speed of flight. The effects are… … Aviation dictionary
compressibility burble — noun : a burble that occurs in the flow about an airplane at speeds approaching the speed of sound … Useful english dictionary
compressibility effect — noun : any of the effects (as abrupt changes in control characteristics) that result from changes in the flow field about an airplane when the velocity at some point in the field reaches the local speed of sound and the air ceases to behave as an … Useful english dictionary
High-speed flight — In high speed flight the assumptions of incompressibility of the air used in low speed aerodynamics no longer apply. In subsonic aerodynamics, the theory of lift is based upon the forces generated on a body and a moving gas (air) in which it is… … Wikipedia
true air speed — The actual speed of an aircraft relative to the air through which it flies (i.e., the calibrated air speed corrected for temperature, density, and compressibility). If the compressibility effects are ignored, then the IAS equals the product of… … Aviation dictionary
air( )speed — The speed of an aircraft relative to its surrounding air mass. The term air speed can mean any one of the following: indicated air speed, calibrated air speed, equivalent air speed, and true air speed. Indicated air speed (indicated air speed) or … Aviation dictionary
limiting speed — i. The maximum indicated air speed permitted, depending on the aircraft configuration. The configuration in this case means clean aircraft, aircraft with external load(s), aircraft with landing gear down, etc. The limiting speed is also specified … Aviation dictionary
limit speed — The maximum permissible indicated air speed for a given configuration. If this speed is exceeded, it may result in aerodynamic departure, structural failure, compressibility problems for nonsupersonic aircraft, loss of directional stability at… … Aviation dictionary
