The inverse solution problem of vehicle motion in maneuvering flight is discussed in which the control inputs can be determined so as to enable a vehicle to perform a specified maneuver. For a nonlinear dynamic system such as a helicopter, improving the mathematical model of helicopter maneuvering flight and the corresponding solution technique is one of the most complex and challenging problems in applied mechanics. In this paper a set of nonlinear equations governing the helicopter in maneuvering flight is developed and solved by using a new inverse solution technique. The inverse solution technique is improved to emphasize nonlinearity and good stability and convergence of the sample calculations of level turn, lateral jink, and pop-up maneuvers for two kinds of helicopters. Beginning with a set of prescribed flight conditions, this inverse solution calculates the flight path, velocity, and other kinematic parameters first, and then the control inputs, flight attitude, and the load factor for the specified maneuvers.
