As a part of the performance improvement programme for the MIG-21 BIS aircraft, HAL Nasik planned to undertake the modification of the existing flap control system for servo operation to incorporate an active manoeuvre load control (ML C) system employing aerodynamic surfaces like combat flaps. The present document details the work done by the Systems Engineering Division in accomplishing the above task sponsored by HAL (NASIK). In the system design requirements, the functional requirements which is been detailed in the flow chart of the combat flap controller is described. The flap command is computed as a function of angle of attack and mach number. Hardware design aspect covers a survey of available flight worthy hardware in the country and the hardware used for iron bird experiments . In iron bird simulate experiments, both hybrid and system integration with hydraulic system has been explained . The results obtained has been verified with system requirements and finally the future course of action is been indicated as per the discussions held between NAL & HAL NASIK), luring the execution of the project.
