NASA and AFOSR(Air Force Office of  Scientific Research)  have launched a standard HPR rocket using a new environmentally safe propellant mixture called ALICE. ALICE is short for Alumninum powder and water ice.

“This collaboration has been an opportunity for graduate students to work on an environmentally-friendly propellant that can be used for flight on Earth and used in long distance space missions,” said NASA Chief Engineer Mike Ryschkewitsch at NASA Headquarters in Washington.  “These sorts of  university-led experimental projects encourage a new generation of aerospace engineers to think outside of the box and look at new ways for NASA to meet our exploration goals.”

The ALICE propellant is a promising new propellant that when optimised could out perform existing propellants.

    Fuel for the engine serves as an ice slurry of aluminum powder in the water.
    This fuel slurry has high energy characteristics. But in the icy engine is frozen, to give it a firm consistency.
    Freezing of fuel for its solidification has the following disadvantages.
    Fuel should be stored in a frozen state. It may be difficult for ballistic missiles, especially for a mobile missile bases. For anti-aircraft missiles or aircraft that do not really.
    Therefore, the scope of the ice fuel is limited.
    Icy fuel is fragile, it can come apart from vibration in flight, or in the process of freezing. For a small experimental rocket fuel fragility is not a problem, but it can become a problem for heavy missiles.
    I am a Russian inventor’s Online, I gave a description of variants of the engine on a metal fuel slurry of water, which has the consistency of a thick gel. gel does not need to freeze, gel-like fuel can be stored at normal temperature .
    Gel fuel is elastic and not brittle.
    Gel fuel must be better to burn through the admixture of organic matter and special oxidants.
    Missiles fired on the gel are more convenient than ice, and have a potentially broader range of applications.
