The potential benefits of the application of modern on-blade control concepts such as variable camber, dynamic twist, and dynamic leading edge slat or trailing edge fiap in rotor control have attracted increased interest. This paper discusses the development of a reduced order airloads model in support of flight mechanics oriented modeling of on-blade control concepts. The paper presents details of the formulated reduced order modeling framework that captures the essential dynamics and aerodynamics of various on-blade control concepts. The paper also presents sample evaluation results for an active trailing edge flap control simulated in FLIGHTLAB. The accuracy of the reduced order model (ROM) was validated against the CFD prediction from which the ROM was extracted. Excellent agreement was obtained including the complicated dynamic stall prediction, which substantiates the reduced order model formulation and NNET based model extraction technique.
