Snap Roll
Aerobatic maneuvers are flight paths putting aircraft in unusual attitudes, in air shows, dogfights or competition aerobatics. Aerobatics can be performed by a single aircraft or in formation with several others. Nearly all aircraft are capable of performing aerobatics maneuvers of some kind, although it may not be legal or safe to do so in certain aircraft. Aerobatics consist of five basic maneuvers: * Lines (both horizontal and vertical), * loops, * rolls, * spins, and * hammerheads. Most aerobatic figures are composites of these basic maneuvers with rolls superimposed. 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. A loop can also be performed by rolling inverted and making the same maneuver but diving towards the ground. It can be ...

Zero Lift Axis
A cambered aerofoil generates no lift when it is moving parallel to an axis called the zero-lift axis (or the zero-lift line.) When the angle of attack on an aerofoil is measured relative to the zero-lift axis it is true to say the lift coefficient is zero when the angle of attack is zero. For this reason, on a cambered aerofoil the zero-lift line is better than the chord line when describing the angle of attack. When symmetric aerofoils are moving parallel to the chord line of the aerofoil, zero lift is generated. However, when cambered aerofoils are moving parallel to the chord line, lift is generated. (See diagram at right.) For symmetric aerofoils, the chord line and the zero lift line are the same.Clancy, L.J., ''Aerodynamics'', paragraph 5.7(a) See also * Angle of attack * Aerobatics * Aerobatic maneuver Aerobatic maneuvers are flight paths putting aircraft in unusual attitudes, in air shows, dogfights or competition aerobatics.

Split S
The split S is an Aerobatic maneuver and an air combat maneuver mostly used to disengage from combat. To execute a split S, the pilot half-rolls their aircraft inverted and executes a descending half-loop, resulting in level flight in the opposite direction at a lower altitude. Description The split S is taught to be used in dogfighting when the pilot has the opportunity to withdraw from battle. It can be an effective tactic to prevent an enemy behind (between four o'clock and eight o'clock positions) from gaining a missile lock-on while one is disengaging from a fight. The split S is contrasted with the Immelmann turn, which is an ascending half-loop that finishes with a half-roll out, resulting in level flight in the opposite direction at a higher altitude. The split S is also called a reversed Immelmann turn and can also be written with a hyphen: split-S. In basic terms, the Immelmann and split S are very similar, both accomplishing the same reversal in course, but th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Immelmann Turn
The term Immelmann turn, named after German World War I Eindecker fighter ace Lieutnant Max Immelmann, refers to two different aircraft maneuvers. In World War I aerial combat, an Immelmann turn was a maneuver used after an attack on another aircraft to reposition the attacking aircraft for another attack. In modern aerobatics, an Immelmann turn (also known as a roll-off-the-top, or simply an Immelmann) is an aerobatic maneuver that results in level flight in the opposite direction at a higher altitude. Historical combat maneuver In World War I aerial combat, an Immelmann turn (named for the German air ace Max Immelmann) was a maneuver used after an attack on another aircraft to reposition the attacking aircraft for another attack. After making a high-speed diving attack on an enemy, the attacker would then climb back up past the enemy aircraft, and just short of the stall, apply full rudder to yaw his aircraft around. This put his aircraft facing down at the enemy aircra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Max Immelmann
Max Immelmann (21 September 1890 – 18 June 1916) '' PLM'' was the first German World War I flying ace.Shores, 1983, p. 10. He was a pioneer in fighter aviation and is often mistakenly credited with the first aerial victory using a synchronized gun, which was in fact achieved on 1 July 1915 by the German ace Kurt Wintgens. He was the first aviator to receive the ''Pour le Mérite'' (colloquially known as the "Blue Max" in his honour), being awarded it at the same time as Oswald Boelcke. His name has become attached to a common flying tactic, the Immelmann turn, and remains a byword in aviation. He is credited with 15 aerial victories. Early life Max Immelmann was born on 21 September 1890, in Dresden, to an industrialist father who died when Max was young. In 1905 he was enrolled in the Dresden Cadet School. He joined the ''Eisenbahnregiment (Railway Regiment) Nr. 2'' in 1911 as an Ensign,Franks et al. 1993, pp. 134–135. in pursuit of a commission. He left the army in ...

Flight Dynamics
Flight dynamics in aviation and spacecraft, is the study of the performance, stability, and control of vehicles flying through the air or in outer space. It is concerned with how forces acting on the vehicle determine its velocity and attitude with respect to time. For a fixed-wing aircraft, its changing orientation with respect to the local air flow is represented by two critical angles, the angle of attack of the wing ("alpha") and the angle of attack of the vertical tail, known as the sideslip angle ("beta"). A sideslip angle will arise if an aircraft yaws about its centre of gravity and if the aircraft sideslips bodily, i.e. the centre of gravity moves sideways.Flightwise - Volume 2 - Aircraft Stability And Control, Chris Carpenter 1997, Airlife Publishing Ltd., , p.145 These angles are important because they are the principal source of changes in the aerodynamic forces and moments applied to the aircraft. Spacecraft flight dynamics involve three main forces: propuls ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yaw Angle
The Euler angles are three angles introduced by Leonhard Euler to describe the orientation of a rigid body with respect to a fixed coordinate system.Novi Commentarii academiae scientiarum Petropolitanae 20, 1776, pp. 189–207 (E478PDF/ref> They can also represent the orientation of a mobile frame of reference in physics or the orientation of a general basis in 3-dimensional linear algebra. Alternative forms were later introduced by Peter Guthrie Tait and George H. Bryan intended for use in aeronautics and engineering. Chained rotations equivalence Euler angles can be defined by elemental geometry or by composition of rotations. The geometrical definition demonstrates that three composed ''elemental rotations'' (rotations about the axes of a coordinate system) are always sufficient to reach any target frame. The three elemental rotations may be extrinsic (rotations about the axes ''xyz'' of the original coordinate system, which is assumed to remain motionless), or intrins ...
