STS-36 launch
« on: 05/13/2006 07:51 PM »
Does anyone know more about the dogleg-manuever performed on STS-36 in order to reach a higher-inclination orbit than achievable by a direct launch from KSC?

It was no different than the 57 degree inclination flights just 4.3 more degrees and range safety waiver

I gather the range still would have been able to take appropriate action if the vehicle would have failed or veered off course?

It did a dog-leg maneuver???? I though it went strait off the pad....
BTW, I read somewere that you can launch the shuttle to a 63.5 orbit off KSC!!!
GLS is go for main engine start!

It's called I/Y or yaw steering. Keeps early part of flight out over water  then yaw steers to proper inclination. Lots of ascent performance margine required for this though. STS-48 used it too for get to 39 degree inclination if memory serves.

Do you know at roughly what T plus time the yaw happens and or the altitude/speed?

You said 57 + 4.3 = 61.3, I said 63.5!

From http://www.chron.com/content/interactive/space/archives/90////051596-12369.0-0.html
"In late January, the space agency disclosed that new studies show the shuttle can be launched as far as 63.5 degrees to the north from Cape Canaveral."
