Variable-Displacement Fuel Pump Designed for ALWT.

摘要

A high-pressure variable-displacement (VD) fuel pump for the Advanced Lightweight Torpedo (ALWT) has been designed and tested. It replaces the fixed-displacement pump, which was determined (from NEARTIP program data) to be noisy and inefficient. Final tests of the VD pump show that this design is capable of meeting the ALWT flow requirement. Recommendations are made regarding further development to ensure longer pump life and consistent performance. (Author)
