Well, I can refer you to the Range Safety Wikipedia entry: Two switches were used, ARM and DESTRUCT. The ARM switch shut down propulsion for liquid propelled vehicles, and the DESTRUCT ignited the primacord surrounding the fuel tanks. In the case of manned flight, the vehicle would be allowed to fly to apogee before the DESTRUCT was transmitted. This would ...

Thrust termination is the goal of Range Safety in the event of an errant rocket. Rendering the boosters inert is considered secondary, when possible. The Range Safety Officers don't rely on the current positions of the vehicle to decide to terminate, but instead are looking at the IIP (Integrated Impact Point) on a map. The IIP is the point where the ...

From your question, I think you're describing an otherwise nominal mission where the launch escape system just doesn't seperate, but the booster is able to keep flying and put the spacecraft into orbit. There are two systems which could have failed: the bolts holding the launch tower and BPC in place the jettison motor to remove the tower + BPC From the ...

I was a missile tech on a SSBN in the '70s and worked on the Poseidon C3 SLBM. This missile had six "Thrust Termination Ports" arranged around the periphery of the second stage motor dome. Each TTP was a 10" diameter fiberglass tube angled outward from the motor dome to the side of the missile with det-cord at each end. When commanded by the ...

Summary: There was no alternative to the launch escape system; it relied on redundancy and testing. But there were two ways to detach the LES. There were two different mechanisms to separate the LES from the command module. During a normal flight, the frangible nuts connecting the legs of the LES to the CM would be detonated. During an emergency escape, ...
