And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.
Unpossible! People who don't know their pronouns can't accomplish anything. Seriously though, on the rotorhead in the bottom pic, it appears that both wires and fluid lines are coming out of the top of the mast. Since the rotor spins at a few hundred rpm (410rpm is max for a Bell412 IIRC) the mast must be one complicated piece to manufacture. Al_in_Ottawa
At the air museum I would spend hours tracing lines on spare engines from an F-4 Phantom and CH-54 we used for static display. Incredible marvel that so much was so compact. Not one superflous part. Incredible design on these engines. Oh, and it all has to be accessible to maintainers without too much trouble.
I think it was Alemaster, a helicopter pilot, over at Wirecutters, who said something like "Helicopter, a loose collection of parts that when put together and in flight attempts to tear itself apart". Or something like that. His description was much more eloquent than mine.
Oh Noes! The work of the dreaded fifty year old white men!

Yes, and there's not one superfulous part on that rotor head.
DeleteMotors run on electricity, that's an engine.
ReplyDeleteYou sound just like my high school shop teacher.
DeleteSo if I understand correctly, you can only register electric vehicles at the Department of Motor Vehicles. Good to know.
DeleteGotta go. I'm taking my motor boat out on the lake this evening.
#3 is neither; it is a rotor head
DeleteSo Elmo, is that a 'jet motor' in the second picture?
DeleteLet me do some research with my DuckDuckGo search motor and I'll get back to you.
DeleteIf something isn't broke on your helicopter, it's about to.

Helicopter: a loose collection of parts, flying in formation.
