Abstract
The innovation in this proposal relates to the use of a generalized framework for prediction of RCS that utilizes a common procedure for computing the signature from a hardbody and its associated plume. The RCS methodology is based on a first principles approach to the solution of the Maxwell’s equations utilizing a Vector Finite Element Method. The framework can be readily applied to predict the RCS signatures for complex three-dimensional hardbody configurations that include fins, multiple nozzles, etc. as well as highly asymmetric plumes that result from missiles flying at an angle of attack and structural interactions of the missile body and plume. Detailed studies will be performed that look at the interference effects of the hardbody, its structural components and the associated plume. Combined hardbody/plume simulations for configurations of interest will be performed and the sensitivity of the integrated RCS signature to hardbody-plume interactions will be evaluated in this proposal.
