The Concept.

What is an Ejection Seat?

In aircraft, an ejection seat or ejector seat is a system designed to rescue the pilot or other crew of an aircraft (usually military) in an emergency. In most designs, the seat is propelled out of the aircraft by an explosive charge or rocket motor, carrying the pilot with it.
Once clear of the aircraft, the ejection seat deploys a parachute

Zero-Zero ejection seat -

Now this is what we want!

A zero-zero ejection seat is designed to safely extract upward and land its occupant from a grounded stationary position (i.e., zero altitude and zero airspeed), specifically from aircraft cockpits.

The zero-zero capability was developed to help aircrews escape upward from unrecoverable emergencies during low-altitude and/or low-speed flight, as well as ground mishaps.

Parachutes require a minimum altitude for opening, to give time for deceleration to a safe landing speed. Thus, prior to the introduction of zero-zero capability, ejections could only be performed above minimum altitudes and air-speeds. If the seat was to work from zero (aircraft) altitude, the seat would have to lift itself to a sufficient altitude.

Zero-zero technology uses small rockets to propel the seat upward to an adequate altitude and a small explosive charge to open the parachute canopy quickly for a successful parachute descent, so that proper deployment of the parachute no longer relies on airspeed and altitude.

The seat cannon clears the seat from the aircraft, then the under-seat rocket pack fires to lift the seat to altitude. As the rockets fire for longer than the cannon, they do not require the same high forces. Zero-zero rocket seats also reduced forces on the pilot during any ejection, reducing injuries and spinal compression.

Way to go, Idaho !

Design Principles.

The Build.

So here is what we need to build.

A rescue seat for the Driver / Pilot.
As this is a ground operated vehicle, it needs to be a 'Zero - Zero" type seat.
This will require the seat to be rocket powered to 'clear' and 'deploy'.
A parachute to land the seat and Driver safely.
"End of Life" or "Terminate Mission" protocol for the safety of bystanders.
"Dead Stop" - Integration to all systems after seat deployment - this is to ensure the safety of all at ground zero.

Further Resources needed:

Rocket technology - to propel the seat 30 m into the air.
Air Bag deployment technology - split second response timing.
Altitude monitoring technology - to deploy parachute at precise moment.
PD technology - Parachute Deployment by means of an explosive charge.
HMD - Helmet mounted display for driver.
Safety Harness / Neck Support / Quick Release System - Seat Evacuation Hardware - SEH
