The program for the complex investigation of the hypersonic flight laboratory (HFL) 'IGLA' in the PGU of TSNIIMASH

Experimental investigations of characteristi cs of the flying models (demonstrators) like "Hyper-X" etc in on-ground test facilities are conducted now in the network of hypersonic technology development. Testing of the scramjet unit on autonomous hypersonic flight lab (HFL) "Igla" of length Ly~8 m is scheduled in CIAMB together with a number of other research organizations. On-ground testing of HFL flight regimes sufficient for beginning of real-flight tests is carried out in a number of facilities 2'3 using models and full-scale vehicle sections of the scramjet to provide vehicle stability, flight control and strength conditions with account for operating scramjet at its autonomous flight. The program, methods and principles of operation of piston gasdynamic unit (PGU) with multicascade compression (MCC) for complex investigation of characteristics of the HFL and scramjet section under conditions closely approaching to the real flight are described in the paper. The first stage of the "Igla" HFL pre-model tests in the PGU-7 for Mach numbers ~ 10,13 are also presented in the paper.
