Axis systems and aircraft motion state quantity; --- Part 3. aircraft geometrical properties; --- Part 4. aerodynamic aircraft, moments, their coefficients and derivative. This section GB/T Part of 416,638. This part of the aerodynamics of common terms used in our country for many years has been collection and screening, and as far as possible with the international most countries Habits consistent air aircraft dynamics in this section some of the terminology and symbols with the national standard GB/T 14410-2008 "flying force Learn concepts, quantities and symbols "in harmony. This Part replaces GB/T 16638.4-1996 "Aerodynamics - Concepts, quantities and symbols - Part 4. Aircraft aerodynamic force Moments their coefficients and derivatives. " Section compared with the GB/T 16638.4-1996 The main changes are as follows. a) increasing the spoiler hinge moment, trim tab hinge moment, the definition of derivatives are estimated lateral force coefficient; b) increasing the hinge moment derivatives are estimated definitions. This part is proposed by the China Aviation Industry Corporation. This part of the jurisdiction of the China Aviation Industry Corporation. This section is drafted.
