Experimental Flight Testing and System Identification of Eurocopter AS365N2 Dauphin Helicopter using CIFER

摘要

In this paper, the test helicopter is modified by installing data acquisition system and air data boom. The test helicopter should be approved by the local civil aviation authority with a special airworthiness certificate. Initially, Eurocopter will perform the mandatory checks for test helicopter like weighing of helicopter, Electromagnetic compatibility (EMC)/Electromagnetic interference (EMI) testing, engine checks and Functional Check Flight (FCF). Once the flight test is complete, Eurocopter will again perform the mandatory checks like weighing, FCF, etc. The local civil authority should issue a standard airworthiness certificate after making a full check up to the helicopter. By using the obtained flight data, system identification is performed by frequency-response method with the help of commercial software known as Comprehensive Identification from Frequency Responses (CIFER).
