Abstract
The present invention provides a particle and a composition for e.g., hypergolic ignition of rocket propellant. The disclosed particle and the composition comprise an energetic fuel additive and an ignition agent wherein the ignition agent is deposited on a surface of the particle.
Claims8
A composition comprising:
- a particle and a fuel,
- wherein said particle is suspended in said fuel,
- wherein said particle comprises an energetic fuel additive and an ignition agent,
- wherein said ignition agent is deposited on at least one surface of said particle, and said ignition agent comprises a metal hydride,
- wherein said energetic fuel additive comprises one or more materials selected from the group consisting of:
- a metal oxide, a metal, a metalloid, and any combination thereof, wherein the ignition agent is in amount such that the mass ratio of the ignition agent to the energetic fuel additive ranges from 0.01 to 2,
- wherein said particle is in the form of a core shell structure, wherein said core comprises said energetic fuel additive and said shell comprises said ignition agent, wherein said particle is hypergolic.
4 more elements
