Gyro-stabilized reflector gun sight developed for the post-WWII deHavilland Meteor and Vampire jet fighters which equipped a number of air forces, including the Royal Air Force and Royal Canadian Air Force.

Function

To present an aiming mark which automatically allows for range, deflection and gravity drop of the bullet stream. [Ref. 1]

Technical

Gun sight of type installed on deHavilland D.H. 100 Vampire 3 aircraft. The general principle that was applied to the development of gyro-stabilized or "predictor" gun sighting is that a gyroscope is used to offset the sight line from the gun line through an angle determined by the rate of turn of the sight line. A gyroscope will resist any rotation of its axis. If a gyro is clamped onto a rod on which is fixed a ring and bead sight, any attempt to follow a crossing target will be resisted by the gyro. The degree of resistance will depend on the target's crossing speed. A gyro sight presents the pilot with a sight line held back by the gyro, whilst the line of flight and guns are in front of this sight line. In other words, if the pilot keeps to the sight line indicated by the gyro, his guns automatically point correctly, in direct relation to the rate of turn. [Ref. 1]
