What is an Ejection Seat?
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.

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.
- 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
