Hi, I've looked through the J7W1 posts for an answer to this question but couldn't find a reference to it - ejection ports for the spent cases - has anyone seen a design blueprint showing ejection ports for the spent cartridge cases please, as these are not modelled and the Type 5 would've been unable to use caseless ammunition?
It is, of course, reasonable to assume that the spent cases from the cannons were collected in receptacles below the guns to maintain the aircraft's balance and avoid 30mm brass from being sucked into air intakes or fouling the prop due to the pusher configuration.
Aparently, no weapons were believed to have been installed on the J7W1 prototypes only dummy guns of the same weight were used!!
From the research I've done the J7W was designed around an array of four 30mm Type 5 autocannon as a counter balance to make landing the canard design more practical and the best use of firepower in order to bring down a B29.
The Japanese Navy, preferred the Type 5 30mm autocannon, a heavier better performing and more powerful weapon. If the war had laster longer, it would have become the standard weapon, fitted in fighters such as the Kyushu J7W. But it saw service in only a few aircraft, being wing-mounted in the Mitsubishi J2M5 and installed in upward-firing installations on some nightfighters, such as the P1Y2-S.
TIA
