Conventional holonomic or nonholonomic constraints are defined as geometric constraints in this paper. If the total energy of a dynamic system can be computed from the initial energy plus the time integral of the energy input rate due to external or internal forces, then the total energy can be artificially treated as a constraint. The violation of the(More)
The flight parameters of ChangGong-91, a light aircraft in the normal category, were estimated from flight tests. The output error method was used to produce aerodynamic coefficients, stability and control derivatives. A flight training device (FTD) was developed based on the estimated flight parameters. Flat earth, rigid body, and standard atmosphere were(More)
