Curtiss-Wright Drive Technology

Development & Manufacture of Electro-Hydraulic & Electromechanical Systems for Military

Curtiss-Wright Drive Technology is a business unit of Curtiss-Wright Defense Solutions. CWDT has more than 50 years experience in the development and manufacture of electro-hydraulic and electromechanical systems for military, industrial and automotive applications.

The Swiss subsidiary company was created in 1999 as a result of the takeover of SIG Antriebstechnik AG.

The company operates primarily as a supplier and off-the-shelf engineering service provider. Swiss precision and know-how is still very much a part of the CWDT philosophy, resulting in products that are global leaders in their field ? for example: targeting and stabilization systems, servo drives and controllers for gun and tank turrets, and ammunition feeder systems. The company also played a decisive role in the development of railroad train tilting technology, and has designed sophisticated dynamic hydraulic solutions for specific industrial purposes. Market activity is becoming more and more focused on commercial, civilian applications. The company possesses further skills in the fields of control electronics, sensors, software, and systems integration. CWDT employs some 90 people at the Neuhausen site, half of whom are engineers.

Flick Rammer

General Description
The demand for increasingly more effective, higher performing, and consequently, more complex weapon systems have accelerated the development of semi- and fully-automatic loading systems for both mobile and stationary gun systems. Requirements such as:
  • burst fire
  • higher rates of fire
  • consistent reliability of loading cycles
  • smooth ammunition handling
  • remote control of weapon systems
  • loading in isolated or poorly accessible compartments
  • crew reduction
have created a need for new solutions.
Flick Rammers were developed specifically to answer these needs and can be installed in a variety of artillery systems:
  • field howitzers
  • self-propelled howitzers
  • fortress guns
Flick Rammers facilitate high rates of fire and guarantee a consistent ramming depth at all elevations. Because of their compact design concept and simple controls, Flick Rammers are eminently suitable for retrofitting. Depending on the space available on the gun and the ammunition loading mode desired, Flick Rammers can be installed in both horizontal and vertical loading arm options. Through the use of a flow control system for speed setting rather than the more conventional pressure type, Flick Rammers provide outstanding advantages:
  • low system pressure (120 bar)
  • high operational safety
  • simple operation
  • high reliability
  • low power consumption
  • low maintenance
  • simple retrofitting
  • minimal dimensions
  • high capacity reserves

Under field conditions, a wide variety of different guns using CWDT Flick Ramming Systems have demonstrated outstanding results, firing thousands of rounds of live ammunition reliably. For example, using a fully automatic fortress gun, only 10 seconds were required to fire a complete 3-round burst.

Flick Ramming System
for M 109 self-propelled gun. CWDT has specifically developed and tested a system which is particularly well suited to retrofitting existing or equipping new M 109 self-propelled guns.

  1. Flick Ramming system installed in an M 109 self-propelled gun in the loading position.
  2. Flick Ramming system in the ramming position.
