Foreword

GB/T 14410 "Flight mechanics - Concepts, quantities and symbols" is divided into nine sections.

--- Part 1. Axis systems and motion state variables;

--- Part 2. Forces, moments, their coefficients and derivative;

--- Part 3. aircraft stability and control;

--- Part 4. flight performance;

--- Part 5. flight measurement;

--- Part 6. Aircraft geometry;

--- Part 7. Flight points and flight envelope;

--- Part 8. dynamic characteristics of the aircraft;

--- Part 9. atmospheric disturbance model.

This section GB/T 14410 Part 2.

The partial modification of the use of ISO 1151-3. 1989 (E) "Flight dynamics - Concepts, quantities and symbols - Part 3. forces, moments and lines Number and Derivatives. " This standard and ISO 1151-3. 1989 as compared to a major increase "dimensionless angle of attack, sideslip angle and airspeed derivative with respect to time, up Lower rudder hinge moment pneumatic, aileron hinge moment "and other terms.

This Part replaces GB/T 14410.2-1993 "Flight mechanics - Concepts, quantities and symbols - Part 2. Forces, moments, their coefficients and Derivative".

Section compared with the GB/T 14410.2-1993 The main changes are as follows.

a) an increase of more than force than the force component than the combined torque than the combined torque components, directly derivative than derivatives are estimated definitions;

b) the symbol M Mach modify M Rao, the term "dimensionless" to "dimension", "vector" to "Vector";

c) modify the terms and definitions have a number of references to other clauses marked;

d) increasing the dimension of the unit, and indicated in the symbol bar;

e) an increase in the English index.
