METHODS AND FACILITIES TO BE USED TO EVALUATE THE AIRCRAFT FLIGHT AND NAVIGATION EQUIPMENT IN FLIGHT TESTS

摘要

The Flight Vehicle (FV) flight tests costs are the major part of all capital expenditures to create it. They are possible to be reduced due to transfer of data, based on which the decision-making may be made for engineering performance definition, tested aircraft to declared requirements conformity, from the flight tests to the mathematical and HIL (Hardware-in-the-Loop) simulating estimation. When taking in consideration that the pilot aircraft batch manufacture costs constitute the major part of tests costs, the number of items in pilot aircraft batch depends, in its turn, upon the number of flight tests, conditioned by the given flight tests termination date the part of the tasks redistribution from flight tests to ground investigation allows reducing the number of flight tests and increasing the flight tests safety. The airborne equipment flight development tests are to be considered as the most hang-the-expense and unreasonable. The installation of under debugged equipment samples in test aircraft is not capable to provide the required flight tests approval and safety.
