Boeing B717 reversers

[edetroit]

Hello All,

A friend of mine is modelling a B717. We are a bit stuck for information and photographs of the B717 reversers (especially the innards)

There appears to be two types of RR engines that powered the B717. BR715-A1 and BR715-C1, I'm guessing this might explain the slight difference in reversers.

I have searched and searched for closeups of these reversers but had not joy.

I thought I'd ask here to see if anyone fancies sticking their head inside a BR715 with a digicam or had any more info or pics please.

Regards

Ed

What software are y'all modelling on, if I may ask?

If you need any help with it, I'd be glad to do so Tho I don't have the pics of the reversers.

Thank you for your reply.
We are using Gmax.
Don't need any help with the modelling, just information/pics about the reversers.

Regards

Ed

If it's any help, the BR700-715 TC quotes the same Boeing part number (715-0021-505) for the thrust reverser on all variants of the engine (-A1, -B1 and -C1).

Okaaayy. But these reversers look different.

As far as I am aware, the engines are the exactly the same. The A version had the low-thrust chip (18.5klb) and the C had the high-thrust chip (21klb). We used to swap chips as the seasons changed and we needed more grunt in the bush.

That IMP picture is very old; Impulse handed over it's 717s to Qantas in the early 2000s, so the components (which do look different, I agree) may have changed over time.

It's very common that when an engine gets a thrust upgrade, all future build engines (and engine hardware) get any necessary improvements to handle the higher thrust loads - that becomes the new 'standard'. There will be an associated Service Bulletin to upgrade any older engines and engine hardware to the new standard - incorporation of said S/Bs is a prerequisite to using the higher thrust rating on any older engines.
Since the differences between the two reversers appears minor, I suspect one is the older mark that doesn't have the higher thrust rating capability improvements incorporated.

Thank you very much Capn Bloggs and tdracer.

You have cleared it all up for us.

My apologies DaveReidUK, I should have thanked you as well.
