Abstract:

Modern control theory is used to find a control scheme to minimize certain flight parameters of an aircraft in a 180-degree turning maneuver. The specific technique is that of the conjugate gradient method. The aircraft is described by a set of nonlinear differential equations. Two problems, constant and near constant altitude, are considered. For each problem, the comparison is made of the flight parameters between aircraft with and without inflight-thrust reversing capabilities showing the inflight-thrust reverser will reduce the radius of turn. A method of simultaneously adjusting the weighting coefficients of the cost functional is shown to be of significant value during the most difficult period of coefficient selection viz, the initial trial solutions.
