The term barrel roll, by itself, most often refers to a helical roll around a straight flightpath, the purpose of which is to slow the relative forward motion (downrange travel) of the aircraft. This can help a defender to force an attacker, who is usually behind the defender, to fly out in front, called overshooting.
The counter to a break is often a displacement roll called a barrel roll attack. A barrel roll consists of performing a roll and a loop, completing both at the same time. The result is a helical roll around a straight flight path. The barrel roll attack uses a much tighter loop than the roll, completing a full loop while only executing 3/4 of a ...
In aerobatics, the cobra maneuver (or just the cobra), also called dynamic deceleration, among other names (see Etymology), is a dramatic and demanding maneuver in which an airplane flying at a moderate speed abruptly raises its nose momentarily to a vertical and slightly past vertical attitude, causing an extremely high angle of attack and momentarily stalling the plane, making a full-body ...
An aileron roll is an unbalanced maneuver. [1] As the roll begins, the aircraft will have a tendency to yaw away from the angle of bank, referred to as "adverse yaw." The pilot will usually need to apply the rudder in the direction of the bank to keep the aircraft balanced. An aircraft performing an aileron roll will actually fly along a ...
Muzzle velocity. Muzzle velocity is the speed of a projectile ( bullet, pellet, slug, ball / shots or shell) with respect to [1] the muzzle at the moment it leaves the end of a gun 's barrel (i.e. the muzzle ). [2] Firearm muzzle velocities range from approximately 120 m/s (390 ft/s) to 370 m/s (1,200 ft/s) in black powder muskets, [3] to more ...
Barrel roll; a combination of a loop and a roll. The flight path during a barrel roll has the shape of a horizontal corkscrew and follows a helical path. Aileron roll; 360° revolution about the longitudinal axis at maximum roll rate. It consists of a pitch-up followed by a roll which is uncontrolled in the pitch axis, resulting in an initial ...
Figure 1 Hard wheel rolling on and deforming a soft surface, resulting in the reaction force R from the surface having a component that opposes the motion. (W is some vertical load on the axle, F is some towing force applied to the axle, r is the wheel radius, and both friction with the ground and friction at the axle are assumed to be negligible and so are not shown.
A barrel roll turn, or simply barrel roll, is a turn that involves casting the arms up and leaping into the air and rotating 360 degrees while airborne. While airborne, the performer's back may be arched and the head may be cast back. It starts and ends with the performer facing forward. Barrel roll turns are commonly used in tap, jazz, and ...
