Multi Nozzle Grid Technology Application to MDA Missile Systems

As the US missile defense capability matures there is a growing need for new technologies that enable smaller packaging envelopes and higher mass fractions with improved performance. One such promising technology is the use of Multi Nozzle Grids (MGN) in place of conventional rocket nozzles. The MGN technology packages an array of small “nozzlettes” that individually exhibit high performance expansion ratios and collectively provide large delivered thrust. An MGN nozzle provides the benefit of reducing conventional nozzle lengths (up to 10:1), reducing system weight while potentially improving overall delivered performance. To demonstrate the benefits of the MNG technology to an MDA missile system Valley Tech Systems (VTS) is proposing a Phase I SBIR program for the conceptual design modeling and establishment of processing methods for an MNG nozzle. This Phase I program will provide the design and analyses foundation to proceed into a Phase II demonstration that substantiate the MGN technology benefits to the MDA missile system.
