Description
The Land Mattress rocket is designed as a barrage rocket for land service use. The motor employed is an adaptation of a 3-in. aircraft rocket motor, the modification consisting of cutting down the tail fins. Loss of stabilization due to the reduced tail surfaces is regained by imparting a spin to the rocket with spiral rails in the barrel of the launcher.
A novel method of varying range is incorporated in this rocket. Two spoiler plates, which consist of metal discs with three equispaced, cut-out segments, are placed face to face and are fitted to a spoiler bush. The spoiler bush is a collar which fits over the top of the Fuze No. 721 and is recessed so as not to foul the protruding ends of the fuze shear wire.
