Monomethylhydrazine Propellant

Monomethylhydrazine (MMH) is a type of liquid propellant fuel and oxidizer that falls under the supply class of Liquid Propellant Fuels and Oxidizers. It is commonly used in rocket propulsion systems and is known for its high performance and stability.

MMH is a chemical compound with the formula CH3NHNH2. It is a clear, colorless liquid with a strong, ammonia-like odor. MMH is highly flammable and toxic, so it requires careful handling and storage.

As a propellant, MMH is often used in combination with an oxidizer, such as nitrogen tetroxide (N2O4), to create a hypergolic propellant system. Hypergolic propellants ignite spontaneously upon contact with each other, eliminating the need for an ignition source.

MMH offers several advantages as a propellant, including high energy density, low freezing point, and good performance over a wide range of temperatures. It is commonly used in spacecraft propulsion systems, including satellite thrusters and maneuvering engines.

In summary, Monomethylhydrazine (MMH) is a liquid propellant fuel and oxidizer that is used in rocket propulsion systems. It is highly flammable and toxic, but it offers high performance and stability for space missions.
