Feasibility Study for Enhanced Lateral Control of the P-3C Aircraft
Abstract
New mission requirements dictate the need to improve the P-3's defensive maneuvering capabilities. Research was conducted to find viable methods of increasing the current roll response of the P-3. First, a flight simulator was used to determine an initial 'target' roll response. Next, a computer code was used to evaluate the aerodynamic effect of varying the size and deflection of the aileron. These results, along with the flight simulator tests, were used to analyze the requirements to reach the target response. Several ways to achieve this goal are discussed. It was found that by increasing the aileron deflection from + or - 20 deg to + or - 25 deg and increasing the aileron chord by 50%, a 58% increase in Ci(total rolling moment coefficient) could be realized. This does not reach the goal of a 100% increase in Ci, but, it does yield a large increase in lateral control response. An increase in aileron size and deflection along with some of the other suggested modifications would certainly approach the desired goal.
