Bladders & Diaphragms
For many applications, a positive expulsion device (PED) such as a bladder or a diaphragm is required to deliver fluid from a tank under specified operational environments. ACE develops, designs, and analyzes PED's for spacecraft and aerospace vehicles. ACE performs experimental investigations of PED characteristics to complement development and design for specific applications. Empirical information is used to support design and analysis so that both the desired fluid expulsion characteristics and the required cyclic service life of the PED can be achieved. ACE incorporates experimentally obtained information into the design of PED's so that the likelihood of achieving system performance objectives is maximized within cost constraints.
