The counter-rotating powerplants of the German World War II Junkers Ju 288 prototype series (as the Bomber B contract winning design), the Gotha Go 244 light transport, Henschel Hs 129 ground attack aircraft, Heinkel He 177A heavy bomber and Messerschmitt Me 323 transport used the same rotational "sense" as the production P-38 did – this has ...
The position of all three axes, with the right-hand rule for describing the angle of its rotations. An aircraft in flight is free to rotate in three dimensions: yaw, nose left or right about an axis running up and down; pitch, nose up or down about an axis running from wing to wing; and roll, rotation about an axis running from nose to tail.
The turn needs to be kept coordinated by applying the correct amount of rudder throughout the maneuver. From a practical point of view, the chandelle may be used to turn an aircraft within a minimal turn radius. As such it is a useful maneuver for pilots of small aircraft who find themselves in a blind valley or canyon.
The aircraft will roll in the direction of the rudder. This will cause the aircraft to sideslip through the roll, keeping the nose pointed at only a shallow angle from the flightpath. The aircraft will appear to slide almost sideways at a slight angle around a very narrow, helical path, more like an imaginary pipe than a barrel.
The three axes of rotation in an aircraft. Flight dynamics is the science of air vehicle orientation and control in three dimensions. The three critical flight dynamics parameters are the angles of rotation in three dimensions about the vehicle's center of gravity (cg), known as pitch, roll and yaw.
The term Immelmann turn, named after German World War I Eindecker fighter ace Leutnant 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.
The aircraft gains speed, and the pilot continues and returns to level flight, travelling in the opposite direction from which the maneuver began. It is also known as a "tailslide", from the yawing turn, which is different from the typical method of turning an aircraft in the pitch axis.
The rudder turns (yaws) the aircraft but has little effect on its direction of travel. With aircraft, the change in direction is caused by the horizontal component of lift, acting on the wings. The pilot tilts the lift force, which is perpendicular to the wings, in the direction of the intended turn by rolling the aircraft into the turn.
