Nose Wheel Design On 717

Fri May 17, 2013 5:40 am

Have noticed a few times the nose wheel on the 717-23S has something behind it. After a bit of research I've found to only see it on the 23S models. Much like this QantasLink one...

Is it something to do with locking the wheel up in the hold? That's about the only thing I can think of..

Unfortunately it's pretty mundane. It's a fender. Keeps the nose gear from spraying water into the engines. On some aircraft there's special ridge molded into the side of (some) of the tires which does the same thing.

Yep. The industry term (that I've always heard) is "spray deflector." The MD-80 has similar devices fitted to the main gear as well.
B-52s don't take off. They scare the ground away.

Thanks for the replies, although I did think it would be something a bit more interested!   Still good to know they didn't leave the chocks on!

You're welcome! -You might find that most A.net members are always happy to please.

For curiosity's sake, you might also like to know that Boeing was offering something similar on the -200 series or their 737 model. It was actually a whole "gravel-kit" that not only consisted of a nosegear deflector,

but also of a tube that blew bleed-air down in front of each engine to prevent FOD
