What is a Propellant Mixer?
- A propellant mixer is a machine that mixes the ingredients of rocket propellants, specifically fuel and oxidiser, to ensure a uniform and reliable mixture for solid rocket motors.
- These mixers, such as planetary mixers, are utilised to combine the raw materials that compose rocket propellant.
- The quality of the mixed propellant directly impacts the performance and reliability of the rocket motor.
Vertical Propellant Mixer FAQs
Q1: What is the best solid propellant?
Ans: The most widely used solid rocket propellant for space applications consists of ammonium perchlorate (70%), aluminium (16%) and binder (14%).
Q2: What are the three types of propellants?
Ans: NASA and commercial launch vehicles use four types of propellants: (1) petroleum; (2) cryogenics; (3) hypergolics; and (4) solids.
Q3: What is known as an oxidizer?
Ans: Oxidizing chemicals are materials that spontaneously evolve oxygen at room temperature or with slight heating or promote combustion.
