ABSTRACTFlight testing is both vital for collecting data for aeronautic research and at the same time fascinating for its contributors. Taking a glider as a versatile test bed example, this paper presents a transnational measurement campaign within the framework of a collaborative project funded by the European Commission. This project Advanced In-Flight Measurement Techniques 2 (AIM²) is a follow-up of Advanced In-Flight Measurement Techniques (AIM) and dedicated to developing and enhancing promising optical metrology for various flight test applications up to an industrial level.The Image Pattern Correlation Technique (IPCT) and infrared thermography (IRT) are two of these modern non-intrusive measurement methods that were further developed and applied to the glider test bed within the scope of AIM². Focusing on optical deformation measurements with IPCT the experimental setup, the flight testing and results are summarily discussed. Gliders are not commonly used flight test platforms, which is why this contribution concludes with some lessons learned in general and especially related to the presented application. The experience to be shared with the flight testing community addresses equipment preparation, data collection and processing as well as how to meet official requirements and perform test flight operations in a dense controlled airspace.

Abstract In the process of civil aircraft airworthiness, analyzing power quality is the key to verify whether the power supply system meets the requirements of the clause. This paper makes deep research on the domestic and foreign power supply quality standard files and detailed introduces the characteristics of the power supply quality standard files. Then, comparative and analysis give suggestions which tally with power supply quality test requirements. Finally, define the special power supply quality test method for the practical engineering specifically, and power supply quality test characteristic in civil aircraft flight test, to provide guidance help for the future civil aircraft models.

Natural Laminar Flow

The achievement of large areas of laminar flow over aircraft engine nacelles offers significant savings in aircraft fuel consumption. Based upon current engine configurations nett sfc benefits of up to 2% are possible. In addition the engine nacelle is ideally suited to the early inclusion of laminar flow technology, being relatively self contained with the possibility of application to existing airframes. In September 1992 a European Consortium managed by Rolls-Royce including MTU and DLR began flight testing of a natural laminar flow nacelle. This programme was later extended by R-R and DLR to flight test a hybrid laminar flow nacelle featuring boundary layer suction and insect contamination protection. The tests evaluated the effects of flight and engine environment, boundary layer transition phenomena, suction system operation and insect contamination avoidance strategies. This paper describes the global conclusions from these flight tests which are a significant milestone leading to the future application of laminar flow technology to engine nacelles.

Flight Deck

The Airline Pilot has little to do with Flight Testing for Certification, in fact, apart from a few specialist pilots in the airlines the average airline pilot takes no part in the Flight Test Programme.Once an aircraft has been certificated, however, the airline pilot spends more time on the Flight Deck and has longer to experience the shortcomings of the Certification Programme than anyone else. He is then the Consumer, the man who spends hours with an expensive piece of machinery strapped to him and who suffers over a long period of time any cockpit design defects. For that reason a large part of this paper will be devoted to, I hope, useful criticism of Flight Deck Layouts as they affect the operating crew member.

The Moment

When I was asked to give this lecture on Civil Flight Testing, I considered in what way any of my experience might be of general help to the Industry.The tests which A. and A.E.E. make on civil aircraft are at the moment of three kinds: —(a)Tests to prove compliance with Air Registration Board requirements for a Certificate of Airworthiness.(b)Development tests for firms in order to suggest modifications to the aircraft occasioned by the results of tests made under (a).(c)Tests made for the Ministry of Supply because some of the aircraft are for Ministry of Supply contracts.
