Abstract
A propellant including a binder, a curative for the binder (whenever necessary), an oxidizer and a fuel additive are provided. The oxidizer has a relatively high value of specific gravity or density and is stable even at relatively high temperatures and is capable of supplying relatively high amounts of oxygen to the fuel additives or the reducing agents in the propulsion material. The propellant provides density-impulses greater than the density-impulses provided by the propellants of the prior art.
Claims14
In combination for producing propulsion,
- a closed combustion chamber having a hollow configuration and including a restricted throat opening to the atmosphere to provide for the passage of combustion gases from the combustion chamber to the atmosphere through the restricted throat,
- a propulsion-producing material disposed in the combustion chamber and having properties of being combusted to produce combustion gases in the absence of atmospheric oxygen in the member and of passing the combustion gases into the atmosphere through the restricted throat in the combustion chamber to produce propulsion of the combustion chamber,
- the propulsion-producing material including:
- a binder providing hydrocarbon linkages,
- a lead compound oxidizer formed from inorganic lead oxidizer salts and having dense characteristics and stable properties at ambient temperatures and through a particular temperature range above ambient, and
- a particulate metal fuel additive having properties of being oxidized by the oxidizer, the binder having a range of percentages by weight between eight percent (8%) and seventeen percent (17%) and the particulate metal fuel additive having a range of percentages by weight between eight percent (8%) and thirty percent (30%) and the remainder constituting the oxidizer.

In combination for producing propulsion,
- a closed combustion chamber including a restricted throat opening to the atmosphere, the to provide for the passage of combustion gases through the restricted throat into the atmosphere, and
- a propulsion-producing material having properties of being combusted to produce combustion gases for escape of the combustion gases through the restricted throat in the combustion chamber to provide propulsion of the combustion chamber,
- the propulsion-producing material including:
- a binder providing hydrocarbon linkages to become oxidized, the binder being selected from a group consisting of polysulfides and carboxy-terminated polybutadiene polymers, polytetrafluoroethylene, fluorothylene-propylene copolymers and acetal homopolymers,
- an oxidizer formed from an inorganic lead oxidizer salt and having dense characteristics and stable properties at ambient temperatures and through a particular temperature range above ambient and having a low heat for formation, and
- a particulate metal fuel additive having properties of being oxidized by the oxidizer, the particulate metal fuel additive being selected from a group consisting of aluminum, beryllium, magnesium and titanium.
