And yes, benzine works as a fuel too! Great additive for methanol. Ah, greater living through chemistry.
Oh yeah! It's a toxic carcinogen too. I wondered where all those brain cells went!
The space shuttle thrusters were mentioned that use monomethyl hydrazine, and nitrogen tetroxide as a hypergolic propellant. The injector plate is about 6 inches in diameter and has several hundred holes about 0.012 diameter. Drilling the holes took 4 days on a CNC that had a really small peck drill cycle. The plate is made of Niobium. Niobium bonds with just about anything and everything and has a 24 step refining process. The shuttle has 38 Primary Reaction Control System (PRCS) thrusters and the nozzle on every one has a different profile to fit the outer skin. There are 6 smaller vernier thrusters for a total of 44. Hint: I worked for the company that made them.
Niobium (columbium) is a real bitch to work with. It was discovered the hard way that if you touched it, it cracked at the touch point when it was welded. Welded with an electron beam welder in a vacuum.
The Marquardt Company made thrusters for just about every satellite and the lunar lander. All of them had a life span measured in seconds. The lunar lander thruster had a rated life of 10 seconds. When the shuttle came along it had a maximum 150 seconds of burn PER misssion. The original specification called for 100 flights with no maintenance. That sure went out the window in a hurry.
The original delivery schedule for the shuttle was hung up on the thruster delivery. Fortunately the main engine took over as the long lead item, then the thermal tile problems took the "heat" off of us.
The shuttle was the first flight vehicle that was reverse speed tested. Other than the really slow drop tests that were more landing tests than anything else, the first flight was from mach 22 to zero! The thrusters are used until the atmosphere is reached and the thrusters start trading off with the flight surfaces.
