![]() For a personal story of one man's ejection, click here. This seat was used successfully at altitude. Manually place his feet into prior to ejection. Mechanisms for the pilot's legs or arms, merely a set of foot guards that the pilot had to This version of the seat did not have any retract This seat was fitted to the early prototypes and the first twenty-six F-104A aircraft. Of the F-104, Lockheed turned to Stanley Aviation Corp. Sub-contracted to other companies that were more experienced in the industry. Have the seats upgraded, and eventually decided to have the seats replaced with a seat ofĪlthough the aircraft manufacturer was tasked with seat development, it was often Luftwaffe, which used the F-104G as a low level attack plane. This was a particular problem to the German These seats served well in USAF service, but were still not considered suitable forĮxtreme low level ejections with high sink rates. Later the seats were replaced with an upward firing seat, once capable catapults wereĪvailable. It also effected the windblast on the pilot. Including the vertical fin at higher speeds. This allowed for the best capability of clearing aircraft structure, ![]() In the early days of the XF-104 program, it was decidedĭue to the limitations of the available ejection seat catapults, the ejection seat shouldįire downwards. Specifications would include such items as minimum/maximum altitude and In those days, the USAF would specify to the aircraft The F-104 ejection seat story is a classic story of the evolution of egress systems over This assures system redundancy by providing dual-line initiation for the canopy-separation charge.The Ejection Site: F-104 Ejection Seats The Ejection Site The Ejection Seats of the F-104 Explosive manifolds, within SMDC line runs, allow output SMDC lines to be initiated from one SMDC input. Inert connectors joining the SMDC lines transfer the explosive stimuli through bulkheads, straight runs, tee connections, and 90-degree bends. During emergency ground egress, without seat ejection, the explosive signal provided by the canopy jettison initiator is blocked from entering the SMDC lines of the seat ejection system by the one-way explosive transfers. ![]() As previously mentioned, during emergency ground egress, seat ejection, or ditching condi-tions, the canopy may be jettisoned by pulling either an internal or external canopy emergency jettison initiator handle. The safe-and-arm seat ejection module for use if the lanyard-operated firing mechanism of the module fails. This signal positions an explosive charge withinįigure 2-4.- Canopy emergency jettison initiator handles. ![]() This fires the initiator to send an explosive signal through a 1.1-second time delay. lanyard for the backup initiator becomes taut and actuates linkage to remove the backup initiator sear. As the canopy leaves the aircraft, theįigure 2-5.- Canopy external jettison initiator handle. The canopy gas generator produces high-pressure gas that forces the canopy hydraulic actuator shaft upward, ballistically jettisoning the canopy. Expanding SMDC lines, routed through the latch hooks, break the canopy latch frangible bolts and allow the hooks to rotate upward, releasing the canopy. This sends an explosive signal through shielded mild detonating cord (SMDC) lines to the safe-and-arm firing pins, canopy-separation charge expanding SMDC, and canopy gas generator. A system initiator is fired by sear removal. System Operation Pulling the pilot or NFO face curtain or secondary firing control handle initiates seat ejection (fig. 2-4), located inside the aircraft or externally (fig. The canopy may be jettisoned without initiating seat ejection by pulling a canopy emergency jettison initiator handle (fig. Through the use of pyrotechnics, the canopy is automatically un-locked and jettisoned when seat ejection is initiated. The canopy must be clear of the cockpit before seat ejection. Canopy emergency jettison systemĭuring emergency conditions that require emergency ground egress, seat ejection, or ditching. 2-3) jettisons the canopy clear of the cockpitįigure 2-3. The emergency canopy jettison system (fig.
