Holy crap, I almost shat myself! There are easier ways of doing that, you know. You don't have to scare the living crap out of people to start a jet engine...
Do ALL Avons use the triple breach starter? Or was there variants that used other systems? Like the Saab Lansen had a license built Avon, but it must have been a bitch to get to the front of the engine to load the cartridges. But it DID have lots of odd vents and scoops, etc. along the fuselage.
In a way, its a 250bhp cordite cartridge which burns for about 2 or 3 seconds. This drives a trurbine at the front of the engine and is geared to the main turbine shaft.
So is that different than an APU turbine? The Harrier has a little mini-turbine engine over the main engine, and uses that to start to engines. I always assumed that it just used regular jet fuel, but I wouldn't know. In fact, I think the F-15 and F/A-18 have that too; it also powers systems while on the line, so they don't need to run power cables to it.
Yea it is different, i work on the apache helicopter. That has an apu for starting the main engines. They both supply air for starting, but in different ways. The apu is itself started from a large hydraulic accumulator. The apu has a air bleed which is then used to turn the main engine over when selected, and also runs the main hyd's and elec's until the engines are up and running. The canberra has the tripple breach start, which is a part of the engine itself. Push button enjoy the ride!
Is this a Canberra? You say that the air comes from a bleed in the APU turbine; do you mean comp. bleed air, or exhaust gas? Would they both work? I've never heard of a "triple breach". Something to do with the three plumes of smoke that come from around the engine on startup? That would be smoke from the cordite charge? You said below something about a "turbine at the front of the engine". Is that a different turbine? When you spin up an engine, is the force put to the comp. or to the turbine?
This gives you three starts. One to set off one to come back and one for luck.
The starter has its own small reaction turbine that was geared to a central output that was placed in the reduction gear in the front bearing housing. The Starter turbine ran at some massive rpm in the 60 or 70,000 rpm. Whiz isn't it?
I agree. NASA was operating one of these out of Ellington field when I lived near there. When I first heard it fly over, I thought it was in trouble. These planes emit the most god awful scream I've ever heard. One wonders where they get the parts needed to keep it in the air. Not to mention it was considered somewhat of a widow maker even in its' hey day.
this is cool, but what is its purpose? i can't see any advantage of this over a standard electric startup. looks timely and expensive (unless it is some kind of backup starting system)

Dear All,
I have some questions about psychology:
(1) Why do we love flying?
(2) Why do we like to click the bottoms on an aeroplane's cockpit?
(3) Why do we enjoy the feeling of powering up an aeroplane?
(4) Why do we like to hear the high-pitch-noise of an aeroplane's engine, especially when powering up?
THANK YOU IN ADAVNCE for your creative ideas and brainstorm!!! :)

Wow, never seen an Avon start that way. Very cool.
We start our avons with either the electric starter, or a modified air turbine starter.
We don't feed the fuel until the engine reaches about 1400 rpm, and the main rotor weighs over a thousand pounds.
Here, it sounds like about that speed is reached in about two seconds, so this video shows some very impressive acceleration.
I woud love to see this in person!

So they just fired the starter without actually igniting the engine?

Check out google, pictures and moving diagrams of how it all works ;)

Triple breach because there are 3 cartridges.
This gives you three starts. One to set off one to come back and one for luck.

How certain are you that the 'god awful scream' wasn't coming from the flight deck, or the passenger compartment?

the cranked the engine over with out fuel
i believe that engine uses a second turbine (powered by exhaust out of high pressure air or solid state rockets) to spool the jet engine

i think its because it's lighter
timely, not really (just slide a charge in and ignite)
it would probably same money in the long run (saving fuel)

Very interesting video. Engine starters sometime are as complex and delicate as the engine itself!
