mach number control
1Critical Mach number — Transonic flow patterns on an aircraft wing showing the effects at critical mach. In aerodynamics, the critical Mach number (Mcr) of an aircraft is the lowest Mach number at which the airflow over any part of the aircraft reaches the speed of… …
2Drag divergence Mach number — The drag divergence Mach number (not to be confused with critical Mach number) is the Mach number at which the aerodynamic drag on an airfoil or airframe begins to increase rapidly as the Mach number continues to increase[1]. This increase can… …
3drag divergence Mach number — The Mach number at which there is a sudden rise in wing drag as a result of the formation of shock waves. Buffet may take place and control difficulty may occur at this Mach number …
4Mach tuck — is an aerodynamic effect, whereby the nose of an aircraft tends to pitch downwards as the airflow around the wing reaches supersonic speeds. Note that the aircraft is subsonic, and traveling significantly below Mach 1.0, when it experiences this… …
5Mach Five — For the song by The Presidents of the United States of America, see Mach 5 (song). : For the Mach speed rating system, see Mach numberThe Mach Five (マッハ号; mahha gō ; lit. the Mach ) is the racing car Speed Racer (Go Mifune in the Japanese… …
6Mach hold mode — In a flight control system, a control mode in which a desired flying speed of an aircraft expressed as a Mach number is maintained automatically. The system is used in high speed aircraft flying at a high altitude. The signal output from sensors… …
7Mach technique — A control technique used by ATC (air traffic control) in which turbojet aircraft operating successively along suitable routes are cleared to maintain an appropriate Mach number for a relative portion of the en route phase of the flight. This is… …
8Mach trim compensator — In a flight control system, an automatic control subsystem that provides the pitch trim of an aircraft as a function of the Mach number. This is to meet the requirement of large changes in trim at or near sonic speed when the compressibility… …
9Mach (kernel) — Mach is an operating system microkernel developed at Carnegie Mellon University to support operating system research, primarily distributed and parallel computation. It is one of the earliest examples of a microkernel, and still the standard by… …
