Integrated Flight and Propulsion Control (IFPC), in combination with thrust vectoring and multimode variable cycle engines, can yield substantial airplane performance benefits. These benefits are dependent on the airplane configuration and can be maximized only when the airplane is designed as a control configured vehicle. Maximum maneuvering benefits are obtained with a highly unstable airplane. The paper describes the conceptual design of a highly unstable airplane, representative of the Advanced Tactical Fighter, featuring a canard, thrust vectoring, multimode variable cycle engines, and IFPC. Several novel IFPC modes are defined, each maximizing the performance metric of interest to the pilot in one or more mission tasks. These modes optimize either excess specific power or fuel economy for specified normal load factor in all prestall flight conditions. Each IFPC mode is characterized by the use of unique trim deflection schedules for redundant control effectors (canard and vectoring nozzles in the present case) that are functions of flight condition, in conjunction with the use of a specific engine mode. Maneuvering performance benefits of several IFPC modes are given.
