Boeing B717 reversers

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.
