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.
Apr 11, 2017 · The coffin corner's real name is the "Q Corner", because "Q" is the abbreviation for dynamic pressure. Coffin corner occurs from the interaction between stall speed and critical mach speed, which are both caused by pressure over your wing.
Oct 30, 2023 · What is the coffin corner? The 'coffin corner' refers to the intersection of a given aircraft's stall speed and critical Mach number. While stall speed is enough of a self-explanatory term, critical Mach number may be a less well-known term.
SKYbrary. In aviation, coffin corner (or Q corner) refers to the point at which the Flight Envelope boundary defined by a high incidence stall intersects with that defined by the critical Mach number.
Jan 1, 2024 · Photo: Dassault. Summary. Coffin Corner refers to the flight region where stall speed is close to the aircraft's critical Mach number, leading to loss of lift and potential catastrophe. High-speed stalls are caused by shockwave formation, while low-speed stalls increase with altitude due to compressibility.
Sep 30, 2020 · The coffin corner is called the Q Corner in the official aviation lexicon, as the letter Q is the symbol for dynamic pressure - the pressure caused by air flowing over the wing. A coffin corner comes into existence as an aircraft moves fast enough and high enough that the pressure starts to equalize between under and over the wing.
