mohawkALSE Posted November 12, 2019 Share #1 Posted November 12, 2019 After a long time of searching for the correct bailout bottle for the Martin Baker Mk-J5 series ejection seat, I found one. The bottle is the standard H-2 style with the regulator section having a few differences. The type for the J5 seat has this flat movable linkage connector and a shorter hose with a 2 pin male quick disconnect fitting. That fitting is also designed to be held in place with a bracket on the right side of the seats bucket. A quick disconnect female fitting on a extension hose connects there with a disconnect lanyard attached to the Rigid Seat Survival Kit. When man seat separation occurs, the crewman and survival kit leave the seat and the hose is disconnected from the seat side hose. When the bottle is correctly rigged up to the right rear of the seat bucket, the activation lanyard is attached to a mechanism that does 2 things. It is connected to a trip lever, which when ejection occurs and the seat is rising, strikes the crossbeam attached to the ejection gun tube to automatically activate the oxygen. Also on the lower portion of the mechanism is another a manual activation line that runs in a conduit along the right of the bucket to a seat mounted "Green Apple". If the aircraft's O2 failed, you can pull this knob and have emergency O2. Link to comment Share on other sites More sharing options...

mohawkALSE Posted November 19, 2019 Author Share #4 Posted November 19, 2019 More detailed breakdown from the J5D seat Mx manual. Good breakdown showing the mechanism that the pull cable connects to allowing the automatic activation with the trip lever (item 30) and the manual activation cable (item 9) running up to the green apple (item 2) Link to comment Share on other sites More sharing options...

mohawkALSE Posted November 19, 2019 Author Share #6 Posted November 19, 2019 Showing the various components and the CRU-60 oxygen block that it attaches to. This bottle still shows its charged and has the safety pin that would be removed before installation. The pull cable only requires 1/4" pull to activate it so that pin is a must currently. Also note the quick disconnect lanyard PN has OV1 in it showing its end use is specifically for the OV-1 Mohawk. Link to comment Share on other sites More sharing options...
