Title: Installation of the engine unit in an armoured full-track combat vehicle
Inventor: STOLLBERG KARL DIPL ING
IPC: F41H7/02
Filed: 1981-04-27
Abstract: In the armoured housing of an armoured full-track combat vehicle having a gun or missile-firing unit installed in a restricted pivoting range, the engine unit assembled in a block is installed leant against a side wall outside the vehicle centre and as high as possible under the upper armoured ceiling. With this installation, ammunition or fuel can additionally be stored in containers underneath the engine unit. Next to the engine unit, a passageway between the combat space and the rear wall can be incorporated over the entire height of the armoured housing. When in danger, the crew can save themselves through this passageway under armoured protection without any physical obstruction. Ammunition or fuel can additionally be stored in the lower part of the passageway, without impairing the escape possibilities. As a result of the proposed, hitherto unused possibilities of installation of the engine unit, the combat capability of armoured combat vehicles having a gun installed in a restricted pivoting range is appreciably increased, without any additional technical outlay, as a result of a larger stock of ammunition or a greater travelling range and the possibility of escape for the crew under armoured protection.
