| With the development of aviation, aerospace, marine, automotive and other fields,the expansion airspace aircraft traffic is getting worse. At present, this problem has gradually become the bottleneck of China’s civil aviation development, which makes civil air transport companies suffer certain economic losses to a variable extent. RVSM,improved this problem to some extent, is first used in foreign countries. For China does not has strict process of RVSM operation, by learning from foreign experiences,omissions and errors are inevitable. Therefore, according to the experience of implementation of RVSM operations abroad, from two aspect of RVSM airworthiness compliance and continuous RVSM airworthiness, this paper is mainly engaged in researching compliance of RVSM operations of China, summarizing foreign research status and related statutes initial airworthiness requirements analysis, verifying the safety of RVSM operations of China, and analyzing and investigating skin waviness measurement methods while increasing to RVSM run critical area.Altitude measurement system is the key system of RVSM operations, which play an important role at the time of the initial RVSM airworthiness and continuing airworthiness.When RVSM initial airworthiness, errors of altitude measurement system are compensated by analyzing relations among static source error, RVSM operational flight envelope and Mach number, which improve accuracy of altitude measurement system and thus achieve initial airworthiness RVSM operations. When RVSM continuous airworthiness, numerical waviness of aircraft key area will affect error of aircraft altitude measurement system, the paper will analyze measurement method of waviness of RVSM operations key area, process data simulate collected from current platform with least square method. The result of RVSM continuous airworthiness is obtained and maintenance requirements of damaged skin area are also proposed.For skin waviness measurements, the experimental data analysis is completed, and processing method of aircraft skin waviness has been verified based on mobile vision measurement. Waviness date is measured by building fit planar of fuselage skin with mobile vision measurement through experiment. Finally, the feasibility of the system in the field of RVSM measurement is verified through experimental method. |
