It also helps that the SR-71 fuel was almost impossible to ignite. It couldn’t be spark ignited, instead they used triethylborane, an pyrophoric liquid that burns in contact with air. It’s also used to ignite rocket engines as its reactive enough to burn on contact with liquid oxygen.
- benj111 8y ago"almost impossible to ignite" .... "pyrophoric liquid that burns in contact with air" Those seem mutually exclusive? Do you mean that triethylborane ignites the fuel?
- benj111 8y agoI don't know why I'm getting down votes for this, its a reasonable question. To answer my own question triethylborane is indeed used to ignite the main fuel. https://www.quora.com/Why-was-Triethylborane-used-as-a-starter-fuel-for-the-SR-71-Blackbirds https://www.quora.com/Why-was-Triethylborane-used-as-a-start...
- refurb 8y agoYou’re getting downvoted because you’re calling out an inconsistency that doesn’t exist. The fuel that doesn’t burn is separate from the pyrophoroc stuff used to start it.
