Abstract
Methods and systems are provided for propelling a vehicle. In an embodiment, by way of example only, a method includes flowing a decomposed hydroxylammonium nitrite (HAN)-based propellant into a chamber, introducing an aspirated non-polar fuel into the chamber, and combusting the decomposed HAN-based propellant and the aspirated non-polar fuel to produce an exhaust gas.
Claims18
A method of propelling a vehicle, the method comprising the steps of:
- injecting a hydroxylammonium nitrite (HAN)-based propellant;
- forming decomposed HAN-based propellant by passing the HAN-based propellant through a bed;
- flowing the decomposed HAN-based propellant into a chamber;
- introducing an aspirated non-polar fuel into the chamber;
- and
- combusting the decomposed HAN-based propellant and the aspirated non-polar fuel to produce an exhaust gas.

A method of propelling a vehicle, the method comprising the steps of:
- injecting a hydroxylammonium nitrate (HAN)-based propellant;
- forming decomposed HAN-based propellant by passing a HAN-based propellant through a bed;
- introducing an aspirated non-polar fuel into a chamber at a first pressure;
- igniting the aspirated non-polar fuel;
- and
- flowing the decomposed HAN-based propellant into the chamber at a second pressure to thereby produce a thrust to propel the vehicle.
3 more elements
A system for propelling a vehicle, the system comprising:
- a vessel that defines a chamber;
- a decomposer positioned in the chamber to divide the chamber into an upstream reception section and a downstream combustion section, wherein the decomposer is adapted to decompose a hydroxylammonium nitrate (HAN)-based propellant provided to the upstream reception section and to provide a decomposed HAN-based propellant to the downstream reception section;
- an aspirator adapted to aspirate a non-polar fuel in order to provide an aspirated non-polar fuel to the downstream combustion section;
- and
- a combustor disposed in communication with the chamber, and adapted to receive and combust the decomposed HAN-based propellant and the aspirated non-polar fuel to produce an exhaust gas.
