Moottoripornoa ja -experimenttaalia

The SR-71's J58s "Starters":

The AG-330 Start Cart, orginally were *Buick wildcat 401 cubic inch V-8 engines developing 400 horsepower.
There were two Buick engines mounted tandem side by side with automatic transmissions. They were coupled together with a steel woven drive belt to drive a vertical shaft that was inserted into the starter mechanism on the bottom of the SR-71's engine.

On engine launch there was one AG-330 Buick for each SR engine. For the first time observer of an SR-71 launch, the engine starts in themselves were almost indescribable.
For one thing there were NO MUFFLERS on the Buick engines.
As the Buick RPM was advanced, Flames almost three feet long erupted from the side of the start cart. It truly sounded like the beginning of the Indianapolis 500.
Combine that sound with the steady increase of SR-71 RPM to engine TEB ignition at 3,200 RPM and then idle aircraft engine speed as the Blackbird comes to life.
*Later switched to big block
  Chevy 454s



J-58, the engine of the SR-71. Easy to spot because of it's unique feature: those largish tubes on the outside allow a big dose of air to bypass the combustion chambers, feeding the afterburner directly. Basically turns it into a ramjet at high speeds.

Vaatii jämäkän testipenkin..

Mitenköhän toi starttikärry "kytketään" siihen suihkumoottoriin startissa...?

Noilla lentomekaanikoilla on varmaan ollut hankaluuksia kävellä palliensa kanssa..
Kytkin on nimittäin tämmönen:

Starttivaunussa käsin SR 71 pohjaan ajettava kytkin.

Muistin että tuo olisi ollut Jaguaarin? No muisti on mitä on ja en tiedä tuosta sen tarkemmin...
