What does the term coffin corner mean?
: one of the corners formed by a goal line and a sideline on a football field into which a punt is often aimed so that it may go out of bounds close to the defender’s goal line.
What is buffet onset?
Buffet develops gradually with an increasing lift coefficient or Mach number, and buffet onset refers to the conditions at which buffet first occurs. As the Mach number increases, the buffet-onset lift coefficient decreases, defining the buffet boundary.
What causes coffin corner?
Coffin corner occurs from the interaction between stall speed and critical mach speed, which are both caused by pressure over your wing. Get too fast, and you’ll exceed your critical mach number. The air over your wings will go supersonic, you’ll pitch down, the aircraft will accelerate, and your wings will fall off.
What is Coffin Corner used for?
Q-Corner or Coffin Corner. A term used to describe operations at high altitudes where low IAS yield high TAS (as indicated by Mach number) at high angles of attack (AOA). The high AOA results in flow separation, which causes buffet.
Why is the coffin corner called the Q corner?
And that region of flight is called the “Coffin Corner”. 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.
Where does stall and overspeed meet coffin corner?
Coffin corner occurs from the interaction between stall speed and critical mach speed, which are both caused by pressure over your wing. So, “Q Corner” is the techie name, but coffin corner sounds more dramatic.
Where is the coffin corner in American football?
Jump to navigation Jump to search. A coffin corner refers to the corner of the playing field in American football just in front of the end zone, usually from the 5-yard line to the goal line.

What do you mean by Coffin Corner in aerodynamics?
Coffin corner (aerodynamics) Coffin corner (also known as the aerodynamic ceiling or Q corner) is the region of flight where a fast 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 the airplane in stable flight.
