COMMERCIAL DERIVATIVE AIRCRAFT AND TURBINE ENGINE

摘要

A Commercial Derivative Aircraft (CDA) is a commercial off-the-shelf produced aircraft with an FAA Type Certificate (TC). The aircraft may be modified for use as a Military aircraft. Military modifications may be fully or partially FAA approved to civil statutes for the purpose of retaining airworthiness certification. The key concept of this paper is that the future of military transport aviation will be based on procurement of commercial derivative aircraft & turbine engine. The purpose of this paper is to examine various methods of civil and military airworthiness systems integration. Military specifications are concerned mainly with performance (payload, range, endurance), while civil standards mainly focus on flight safety. This paper discusses certification procedures and airworthiness requirements applied to CDA. Differences between civil and military approach to aircraft flying qualities, structure, avionics, and turbine engine certification and development of harmonized procedures for certification of CDA are examined. Also explored are areas of weakness with the current certification processes. Wright aircraft was the first powered commercial derivative aircraft to be purchased by the military. It was also the first performance based military contract for a power aircraft with a requirement to exceed 40 MPH (the Wright aircraft flew at 42 MPH).
