Abstract
This paper reports the results of a program to develop a pneumatic actuation system for an experimental ejection seat trainer. The device was developed under contract to the U. S. Naval training Device Center, Port Washington, New York.
A method of pneumatic open loop flow and pressure control is presented which results in predictable load dynamics during the ejection process. Close control of maximum rate of acceleration and maximum acceleration is obtained for a wide range of load weights.
System analysis and individual component designs are discussed. Test data and calibration procedures are also presented.
Although the present device is highly specialized, the design methods described in this paper are applicable to any high speed pneumatic ejection system requiring close control of load dynamics.
