Abstract:

The test program included the following objectives Conduct temperature survey on an instrumented T-38 aircraft, including a malfunction pump condition. Determine pilot corrective procedure Simulate aircraft thermal environment on Northrop Hydraulic System Test Stand Establish repeatable test techniques Test servovalves having lap leakages of 3, 15, and 40 ccmin - approximately four valves Correlate valve spool force and control stick force to lap leakage variation Rework tight valves and retest to verify lap leakage criteria.
