The disconnect provides a path for SMDC detonation to the canopyįigure 2-11.-Internal canopy jettison handle.īallistic components and provides a disconnect point when the canopy is jettisoned or removed for maintenance. The emergency escape disconnect is located under the canopy deck. The transfer valve acts as a check valve to prevent the backflow of SMDC detonation to the seat components. The one-way transfer valve is located on the ballistic panel in the upper equipment bay. The initiator receives inputs from either the internal canopy jettison lever or external canopy jettison handles to initiate the jettison sequence. The canopy jettison shielded mild detonating cord (SMDC) initiator is located below the canopy jettison lever. 2-11.) The lever gives the pilot the capability of starting the emergency canopy jettison sequence from inside the cockpit. Named Phantom II in 1959 and redesignated F-4A in 1962 45 built. F4H-1F (F-4A) Two-seat all-weather carrier-based fighter for the US Navy, J79-GE-2 and -2A engines with 16,100 lbf (71.6 kN) of afterburner thrust each. The internal canopy jettison lever is located to the left of the main instrument panel. Operating either the seat pan or face blind firing handles initiates aircraft canopy jettison, the main gun located at the rear of the seat then fires. Two prototypes for the United States Navy, first flown 1958. This single, common cable runs through the bulkhead into the cockpit, where it connects to the internal canopy jettison lever linkage.įigure 2-10.-External canopy jettison handle. The cables are routed through the gun bay and are joined to a common cable at the cockpit forward pressure bulkhead. the front in order to jettison the canopy as well the middle where the actuator is. 2-1 and 2-10.) Each handle is attached to approximately 8 feet of cable. I think the F-4 Phantom is one of the only fighter planes with a. The external canopy jettison handles and cables are stowed behind doors on each side of the aircraft near the radome. This is accomplished by pulling the ejection control handle on the ejection seat.īefore discussing the internal and external methods of jettisoning the canopy, a description of the system's components is needed.Įxternal Canopy Jettison Handles And Cables It can also be jettisoned by initiating ejection.
The canopy can be jettisoned internally or externally without initiating seat ejection. The set comprises of resin and PE parts for windscreen, forward-, centre- and rear canopies and includes canopy actuator jacks, safety uplocks (optional installation), detailed downlocks, forward and rear compasses and. Detail parts for the inner canopies on F-4 Phantoms. The canopy swung open and hit the wing, shattered, but stayed attached in the open position So I think you are you are right in supposing that the hinge system will not allow clean separation. The emergency canopy jettison system provides the capability to ballistically jettison the canopy in case of an emergency. F-4 Phantom II canopy details - for Hasegawa kits. One G-200 I know of had the canopy come open in flight near VNE due to a latch pin guide failure. Learning Objective: Recognize the system components and procedures for emergency canopy jettison.
