Method of Enhancing Microthruster Nozzle Performance

Summary

One of the problems involved with shrinking the propulsion system is that thruster nozzles do not work efficiently when shrunk to a smaller size. Researchers at Purdue University have addressed this problem and developed a new design for a microthruster nozzle that can provide more thrust than existing designs. By better utilizing back pressure, the new nozzle design is able to produce more thrust without the use of any more fuel, reducing the weight and increasing the lifespan of equipped satellites.

Technology Benefits

Improved nozzle performance - simulation models have achieved 100%+ thrust improvementExtended fuel life - shorter thrust required More cost effective - minimal modification to existing microthruster designsWorks with multiple thruster typesAllows for use of conventional nozzlesNo temperature limitations
