The Mk.7 seat was developed from the earlier Mk.5 design by the addition of a rocket pack to enable zero-zero capability. [1] A large upgrade program to retrofit Mk.7 seats to all Lockheed F-104 Starfighter aircraft in German Air Force service was initiated by Johannes Steinhoff in late 1967, this measure improved the type's safety record and several other European nations operating the ...
The Mk.4 seat was designed as an improved, lightweight version of earlier Martin-Baker seats for installation in a range of lighter, smaller aircraft types. [2] Improvements included a single combined seat and parachute quick release fastener (QRF) and a snubber mechanism to allow crews to lean forward without loosening the harness. [ 2 ]
The bubble canopy of a Lockheed Martin F-22 Raptor Canopy of an F-22 Raptor. An aircraft canopy is the transparent enclosure over the cockpit of some types of aircraft.An aircraft canopy provides a controlled and sometimes pressurized environment for the aircraft's occupants, and allows for a greater field of view over a traditional flight deck.
Canopy breaking horns were added to allow ejection through an unjettisoned canopy. [2] Two aircraft types operated by the Royal Norwegian Air Force , the RF-84F Thunderflash and the F-86D Sabre , were retro-fitted with Mk.5 seats at the Martin-Baker company's home airfield at Chalgrove .
A warning applied on the cockpit side of some aircraft using an ejection seat system intended especially for the maintenance and emergency crews. The "standard" ejection system operates in two stages. First, the entire canopy or hatch above the aviator is opened, shattered, or jettisoned, and the seat and occupant are launched through the opening.
The Mk.9 seat is considered by the manufacturer as the culmination of their earlier designs. It features only one firing handle (the face blind handle being deleted) and a new explosive gas system to operate canopy jettison, harness retraction and main gun firing, dispensing with previous mechanical systems of rods or cables.
On many high-performance military aircraft, the canopy is an integral part of the ejection seat system. The pilot cannot be ejected from the aircraft until the canopy is no longer in the path of the ejection seat. In most ejection seat equipped aircraft, the canopy is blown upwards and rearwards by explosive charges.
The Martin-Baker Mk.1 is a British ejection seat designed and built by Martin-Baker. Developed in the late 1940s it was the first in the line of production Martin-Baker seats for military aircraft. Ground and air testing of earlier designs resulted in the first successful test ejection of a company employee in July 1946.
