ROCKET TARGET: (RT) |
|
As a target for anti-aircraft gunners, the rocket target is porjected into the air with speeds and courses approximating those of an aircraft in flight and attack. It consists essentially of a rocket propulsive unit to which are attached large stabilizing fins, arran-ged for maximum visibility. |
|
The rocket targets are referred to by their Mark number (old designation) or by their assembly number (new designation) as indicated below. They all consist of a simple rocket motor with three large fins which consists of wooden frames and light weight fibre board. The fins are 120° degrees apart, each attached by two lugs. |

(a) The Mk 1 and 2 consists of a Motor 36 inches long to which fins 18 inches by 34 inches are attached. An electrical connection is made by standard 110 volt plug. Mk 1 is standardized at 425 m.p.h. and the Mk 2 at 300 m.p.h. On same models a screamer is put over the nose end. |
|
(b) The Mks 3 and 4 differs from the Mks 1 and 2 in construction details: the motor is heavier and the fins are held on by threaded studs instead of lugs. The ballistics are similar, Mk 3 is like Mk 1, and Mk 4 is like Mk 2. |

DRIFT SIGNAL ROCKETS: |
|
Four 3.0" drift signal service rockets for retor-firing have been developed. All of these rockets use the 1.25" motor and have a total weight of 4.5 to 4.8 pounds. The firing of the motor of the drift signal rocket initiates a delay train in the signal which ini-tiaties the flare some 10 to 20 seconds later. The motor seperates from the signal dur-ing the free fall the signal floats in water, burning for 10 to 15 minutes. They are laun-ched from the aircraft launcher Mk 2. |
