Abstract:

The concept of a new test facility to evaluate the underwater launch and flight performance of full-scale missiles and associated launcher systems is described. Results from preliminary studies on estimates of the platform dimensions hydrodynamic characteristics, and platform response to a missile launch impulse are included. The VSAERO panel method code was used to generate hydrodynamic force and moment coefficients for the condition of steady tow at 5 knots. These coefficients were then used to evaluate the platform trim stability under steady tow conditions. Calculations indicate that the platform is stable during all three phases of operation missile in tube, empty tube, and tube fully flooded. Preliminary estimates of the platform response due to a launch impulse show a recoil that is not expected to significantly alter the fidelity of the in-tube trajectory data.
