The recoils system of the M1A2 SEP tank serves what four main purposes?
|
1. To absorb recoil energy
2. To provide a fixed length of recoil through all angles of elevation. 3. To return the gun to battery through all angles of elevation 4.To hold the gun in battery through all angles of elevation |
|
|
The recoils system is know as what?
|
The Concentric Hydrospring Constant Recoil System
|
|
|
What does concentric mean?
|
Concentric means that the recoil system and the gun tube have a common center.
|
|
|
What does hydrospring mean?
|
The recoil system uses fluid displacement to absorb recoil energy and spring tension to return the gun to battery.
|
|
|
What does contant recoil mean?
|
The recoil system provides a fixed or constant recoil of 12 inches through all angles of elevation
|
|
|
The recoils system constist of what four parts?
|
The piston, gun cradle, recoil spring, and the replenisher.
|
|
|
The replenisher is known as what?
|
The open system, gravity fed, self venting, translucent plastic replenisher.
|
|
|
What three purposes does the Replenisher serve?
|
1. Allows the crew to monitor the fluid level in the recoil system.
2. Allows the crew to add or drain fluid as needed. 3. Replensihes the recoil system during firing. |
|
|
What is the piston?
|
A machined cylinder tha is attached to, and moves with the gun during recoil and counter recoil.
|
|
|
Descibe the Throttlling plate?
|
Located near the forwar end of the piston, machined surface, has eight throttling grooves machined into it.
|
|
|
The gun cradle does what?
|
Encases the recoil system and does not move with the gun druing recoil or counter recoil.
|
|
|
The gun cradle has what?
|
A tapered internal diameter to achieve a measurement just under that of the the throttling plate when the gun is in battery.
|
|
|
The gun cradle contains how much FRH?
|
Approximately 10.3 gallons.
|
|
|
How tall is the recoil spring?
|
41 inches
|
|
|
What is the installed height of the recoil spring?
|
24.88 inches
|
|
|
What is the compressed height of the recoil spring at firing?
|
12.88 inches
|
|
|
Recoil spring serviceability is measured by?
|
the spring compression rate, which is 300Lbs/in.
