In Plane Crazy the player pilots a fast, cartoon-like plane, built for speed across a variety of levels. The objective of each level is to reach the end as fast as possible. Planes either bounce or explode when they come into contact with other structures, terrain, or even other planes. They then respawn, invincible for a short amount of time.
SLOP allows aircraft to offset the centreline of an airway or flight route by a small amount, normally to the right, so that collision with opposite direction aircraft becomes unlikely. In the North Atlantic Region pilots are expected to fly along the oceanic track center-line or 1 or 2 nautical miles to its right, randomly choosing one of ...
Instead, a close copy, known as the Bell X-5, was constructed with wings that enabled the sweep angle to be altered mid-flight. As the wing swept back, the root also slid forwards, maintaining the centre of lift in a constant position. [10] A variable-sweep wing of this sliding type was flown on the prototype Grumman XF10F Jaguar in 1952 ...
A Boeing 737 uses an adjustable stabilizer, moved by a jackscrew, to provide the required pitch trim forces. Generic stabilizer illustrated. A horizontal stabilizer is used to maintain the aircraft in longitudinal balance, or trim: [3] it exerts a vertical force at a distance so the summation of pitch moments about the center of gravity is zero.

A straight-winged North American FJ-1 flying next to a swept-wing FJ-2 in 1952.. There are three main reasons for sweeping a wing: [1] 1. to arrange the center of gravity of the aircraft and the aerodynamic center of the wing to coincide more closely for longitudinal balance, e.g. Messerschmitt Me 163 Komet and Messerschmitt Me 262.
A loop is when the pilot pulls the plane up into the vertical, continues around until they are heading back in the same direction, like making a 360 degree turn, except it is in the vertical plane instead of the horizontal. The pilot will be inverted (upside down) at the top of the loop.
Thus, the general offset surface shares the same tangent plane and normal with and (()). That aligns with the nature of envelopes. That aligns with the nature of envelopes. We now consider the Weingarten equations for the shape operator , which can be written as ∂ n → = − ∂ x → S {\displaystyle \partial {\vec {n}}=-\partial {\vec {x}}S} .
The NK-110, which was tested in the late 1980s, had a contra-rotating propeller configuration with four blades in front and four in back, like the NK-12. Its 190-inch propeller diameter (4.7-metre) was smaller than the NK-12's 220–240 in (5.6–6.2 m) diameter, but it produced a power output of 21,007 hp (15,665 kW), delivering a takeoff ...
