Patent number: 9273554Abstract: A high efficiency energy conversion system disclosed herein incorporates a piston assembly including a sealed cylinder for storing a working fluid and an energy conversion element attached to the piston assembly. A kinematic mechanism such as a cam lobe or a scotch yoke may be used as the energy conversion element. In one implementation, the kinematic mechanism may be configured to provide rapid piston expansion in a manner so as not to allow the expanding working fluid inside the piston to achieve thermodynamic equilibrium. In an alternate implementation, the kinematic mechanism is further adapted to generate a compression stroke in a manner to provide the working fluid inside the piston to achieve thermodynamic equilibrium conditions throughout the compression stroke.Type: GrantFiled: August 3, 2011Date of Patent: March 1, 2016Inventors: Gregory S. Mungas, Christopher Mungas, Gregory Peters, Kenneth Doyle

Patent number: 8572946Abstract: Propellants flow through specialized mechanical hardware that is designed for effective and safe ignition and sustained combustion of the propellants. By integrating a micro-fluidic porous media element between a propellant feed source and the combustion chamber, an effective and reliable propellant injector head may be implemented that is capable of withstanding transient combustion and detonation waves that commonly occur during an ignition event. The micro-fluidic porous media element is of specified porosity or porosity gradient selected to be appropriate for a given propellant. Additionally the propellant injector head design integrates a spark ignition mechanism that withstands extremely hot running conditions without noticeable spark mechanism degradation.Type: GrantFiled: July 13, 2012Date of Patent: November 5, 2013Assignee: Firestar Engineering, LLCInventors: Gregory S. Mungas, David J. Fisher, Christopher Mungas

Publication number: 20090133788Abstract: Compositions and methods herein provide monopropellants comprising nitrous oxide mixed with organic fuels in particular proportions creating stable, storable, monopropellants which demonstrate high ISP performance. Due to physical properties of the nitrous molecule, fuel/nitrous blends demonstrate high degrees of miscibility as well as excellent chemical stability. While the monopropellants are particularly well suited for use as propulsion propellants, they also lend themselves well to power generation in demanding situations where some specific cycle creates useable work and for providing gas pressure and/or heat for inflating deployable materials.Type: ApplicationFiled: November 10, 2008Publication date: May 28, 2009Applicant: Firestar Engineering, LLCInventors: Gregory Mungas, David J.
