A microfabricated valve with no moving parts. In one embodiment, the valve includes a reservoir of a liquid that is in fluid communication with an outlet channel having a throat that is less than 100 microns wide. Preferably, the channel is an elongated slit. The configuration of channel is adapted and configured such that surface tension of the liquid prevents flow out of the channel. A heater increases the temperature of the meniscus of the fluid, until a portion of the fluid is ejected from the channel. The ejection of the fluid creates both a thrusting effect and a cooling effect.

A gas turbine engine includes devices, systems, and methods for design and operation of stabilizing heat exchangers for gas turbine engines in consideration of near supercritical fuel flow conditions.

System and method for stabilizing transcritical air-to-fuel heat exchange

A composite solid rocket propellant comprising a fuel, an oxidizer and a dicyclopentadiene binder is provided. The dicyclopentadiene binder may be mixed with the fuel and oxidizer as a monomer and then polymerized after mixing to form the composite solid propellant. The composite solid propellant may also comprise plasticizers, triphenylphosphine, lecithin or combinations thereof. Methods for making the composite solid rocket propellant of the present invention are also provided.
