Engineering Flight Test. TH-55A Primary Helicopter Trainer Limited Performance Evaluation

Samuel R. Schwartz, Donald P. Wray

Open publisher page 1 citations

Abstract

Abstract : A limited performance evaluation of the TH-55A helicopter was conducted in order to determine compliance with contract performance guarantees. Sixteen productive test flights were conducted. All performance guarantees investigated during this test were equaled or exceeded. Flying qualities were investigated qualitatively during the performance tests and were satisfactory except for excessive longitudinal trim change required during autorotational entry.
