Testing of a microrocket engine turbopump
Advances in microfabrication suggest its application to rocket engines. A MEMS thrust chamber producing 50 N of thrust at design point was previously developed that requires propellants pressurized as high as 300 atmospheres. Hence the need for turbopumps at the MEMS scale. A demonstration …

Characterization of heat transfer rates in supercritical ethanol for micro-rocket engine regenerative cooling
… in the cooling passages of a silicon fabricated MicroRocket engine were duplicated. These included conditions of temperature, pressure, film Reynolds number, bulk Nusselt number, and heat flux. The pressures investigated were 100atm and 300atm, corresponding to reduced pressures of 1.62 and 4.86 …

Experimental investigation of microfabricated bipropellant rocket engines
… thrusters of reduced mass will be required. Microrocket engines could provide a low mass, high specific impulse, modular answer to these needs. These small rocket engines would produce thrust of order of 10's of Newtons at a thrust-to-weight of over 1000, over 10 times the thrust-to-weight of …

A systems study of very small launch vehicles
… All vehicles are based on a version of the MIT microrocket engine, a micro-scale rocket engine fabricated in silicon, and weighing 2 g. The engines use nitrogen tetroxide and hydrazine as propellants which are pump-fed to the engine using micro turbopumps. Following the performance study, a 77 …

Experimental Investigation and Modeling of Scale Effects in Micro Jet Pumps
<p>Since the mid-1990s there has been an active effort to develop hydrocarbon-fueled power generation and propulsion systems on the scale of centimeters or smaller. This effort led to the creation and expansion of a field of research focused around the design and reduction to practice of Power MEMS …
