High-speed flight and compressibility effects Most of the jet transports in the world travel in the transonic region. On average, a typical jetliner cruises at speeds ranging from 78% to 85% speed of sound.

WebSep 15, 2024 · The Coffin corner is the altitude at which a plane's stall speed is close to Mach 1, the speed of sound (but still below, at the critical Mach number). What accounts …
WebThe most dramatic sounding is coffin corner—the edge of the flight envelope experienced by high speed, high altitude jets. It occurs where the stall speed (Vs, which increases with altitude) meets the Maximum Mach Number (Mmo, which decreases with altitude). WebSep 9, 2024 · Coffin corner Pilots who ascend too far in a high altitude flight can experience a condition known as coffin corner, in which an airplane can stall if its speed is reduced, but if its speed is increased, it will reach a critical Mach number limit, causing shock waves to form on particular spots usually over the wings.
WebJul 19, 2024 · 13. Yes. The peak is the actual coffin corner. That's why it is called a corner. In the coffin corner the aircraft cannot climb any higher, which is a definition for the absolute ceiling. Going any faster will reduce L/D and cause the aircraft to sink; that Mach effects are involved is of minor importance. Going slower will also decrease L/D ... As you approach the aircraft's maximum ceiling, you'll find that MMO and stall speed meet, or at least get close. Most of today's jets have a fairly wide margin between stall and MMO, but a great example of a coffin corner aircraft is the U-2. At high altitudes, the U-2 can have as little as a 5 knotsbetween … See more As you climb, the air becomes less dense, and your wings need more airflow to generate the same amount of lift.
