Load factor (aeronautics) In aeronautics, the load factor is the ratio of the lift of an aircraft to its weight [1][2]: § 5.22 and represents a global measure of the stress ("load") to which the structure of the aircraft is subjected: where. is the weight. Since the load factor is the ratio of two forces, it is dimensionless.
A chart of velocity versus load factor (or V-n diagram) is another way of showing limits of aircraft performance. It shows how much load factor can be safely achieved at different airspeeds. [3] At higher temperatures, air is less dense and planes must fly faster to generate the same amount of lift.
Coffin corner (aerodynamics) 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.
Wing loading is a useful measure of the stalling speed of an aircraft. Wings generate lift owing to the motion of air around the wing. Larger wings move more air, so an aircraft with a large wing area relative to its mass (i.e., low wing loading) will have a lower stalling speed.
The airspeed at which the aircraft stalls varies with the weight of the aircraft, the load factor, the center of gravity of the aircraft and other factors. However, the aircraft normally stalls at the same critical angle of attack, unless icing conditions prevail. The critical or stalling angle of attack is typically around 15° - 18° for many ...
Stall (fluid dynamics) Airflow separating from an airfoil at a high angle of attack, as occurs at a stall. In fluid dynamics, a stall is a reduction in the lift coefficient generated by a foil as angle of attack exceeds its critical value. [1] The critical angle of attack is typically about 15°, but it may vary significantly depending on the ...
A steep turn increases the load factor of an aircraft. Simply put the aircraft feels heavier due to the effect of centrifugal force. At a 45 degree bank angle the load factor of an aircraft is 1.4 i.e. the aircraft effectively becomes 40% heavier. This requires the pilot to exert backward pressure on the flight stick or column to raise the nose ...
First flight. 23 December 1974; 49 years ago (1974-12-23) The Rockwell B-1 Lancer[b] is a supersonic variable-sweep wing, heavy bomber used by the United States Air Force. It has been nicknamed the "Bone" (from "B-One"). [2][3] As of 2024, it is one of the Air Force's three strategic bombers, along with the B-2 Spirit and the B-52 Stratofortress.
