V/STOL Performance, Stability and Control Requirements from an Operations Analysis Viewpoint
This paper considers performance, stability, and control requirements in terms of their influence on the mission effectiveness and program cost of V/STOL weapon systems; hence, their cost-effectiveness. Performance, stability, and control are among the characteristics that determine the size, weight, and complexity of an aircraft, and ultimately, therefore, its cost. These factors also affect mission effectiveness by their influence upon the availability and survivability of the aircraft and accuracy of its weapons. “Operations Analysis” techniques are required for combining these interrelated factors to evaluate cost-effectiveness. An application is presented for an armed tactical support V/STOL aircraft. Three types are compared: pure helicopter, compound helicopter, and tilt wing.
