Landing Gear 777-300ER

Tue Nov 19, 2002 11:29 pm

I understand that in order to get 1.5 degree increase on rotation without a tailstrike, the 300ER will actually rotate on the last set of tires on each main bogie. Apparently a hydraulic brace has been engineered to allow the aircraft to rotate on it's 'heels'.

I'm sure I read this from a credible source, but I can't place it.
Is this correct?

I remember reading this in AW&ST.

I'm not sure if Boeing actual did it. It should be easy to tell when we get better pictures.

I'm pretty sure they had to.

I recall they mentioned they needed the extra degree to create the extra lift necessary to satisfy their takeoff length guarantees...

The gear looks the same to me...(not that I would know what to look for...)

The Vmu tests should be very interesting to see!

Hey.
Thanks!
Appreciate it.
Ok...it doesn't look the same.
I guess that ends the speculation....

Greg,

You should trust in yourself more! That is actually a very good description of what was done. As the pictures show, the 777-300ER will actually physically lift its front two bogies off the ground during rotation, gaining a greater degree of lift on the wings and thereby cutting down field length.

Should be interesting to see in practice!

Regards,

Rejected? Oh man, that's a great pic! Thanks for sharing!

could the front wheels go down instead. i am not specialist but to drop the front wheels would help the front of the aircrafy to raise ??

A bit 'off the track' question. Does the A340-600 rotates on same rules?

Brons2: Thanks for the compliment  Wink/being sarcastic
