It is presumed that the leg linear velocity l does not contribute significantly to the horizontal velocity at liftoff.
There is no velocity discontinuity at liftoff and no discontinuities in the position variables at all for the onelegged hopper.
We also have imposed a lower bound on the trunk forward speed at all points, and bounds on the leg inclination angle at touchdown and liftoff instants.
Cryogenic propellants (liquid oxygen oxidizer, and liquid hydrogen fuel) need to be continuously topped off (replace boil-off) as scheduled liftoff approaches.
The cause of the crash was determined to be a premature liftoff, followed by a stall and mush into a 12-foot embankment.
Five seconds after liftoff, the left engine fire alarm sounded in the cockpit.
At this point, the volume of enemy fire intensified, hitting the helicopter and causing it to crash shortly after liftoff.
Four seconds after liftoff, the engine overheated and burned through its gas generator, severing an oxidiser line.
Orbiter mass at liftoff was 247,129 pounds (112,096 kg) including payload.
For vertical launch of a rocket the initial thrust at liftoff must be more than the weight.
At liftoff, these engines will generate a total of 130000 kg of thrust.
Impact with the ground occurred 30 seconds after liftoff.
V is simply the integral under the shock acceleration curve, equivalent to the liftoff velocity of the object undergoing shock loading.
Approximately fifteen seconds after liftoff, the rocket fell back to the ground and exploded.
The second strike, at 52 seconds after liftoff, knocked the onboard guidance platform offline.
