WW II Imperial Japanese Navy Aircraft – VENTURI TUBE – MXY-7 Ohka – VERY RARE!


Out of stock


You are bidding on a SUPERB and VERY RARE example of a WW2 Imperial Japanese Navy Aircraft Venturi Tube!  This was SPECIFICALLY used on the Yokosuka MXY-7 Rocket Powered Aircraft!


This item was located on outer port fuselage and producing the vacuum to operate gyroscopic instruments (turn/bank, directional gyro and artificial horizon).  It is mounted on the fuselage, parallel with the longitudinal axis of the aircraft. As the aircraft moves through the air, suction is created in the venturi throat.  Since the venturi throat is connected by a tube to the gyro instrument case, air is sucked out of the instrument, causing air to enter an inlet port and strike the gyro rotor, which then spins rapidly and activates the instrument. 

The Yokosuka MXY-7 Ohka (??, Oka, “cherry blossom”; ??in modern orthography) was a purpose-built, rocket-powered human-guided attack aircraft employed by Japan against Allied ships towards the end of the Pacific War during World War II. Although extremely fast, the very short range of the Ohka meant that it had to be carried into action as a parasite aircraft by a much larger bomber, which was itself vulnerable to carrier-borne fighters. In action during the Battle of Okinawa in 1945, Ohkas were able to sink or damage some escort vessels and transport ships but no major warships were ever sunk. Improved versions which attempted to overcome the aircraft’s shortcomings were developed too late to be deployed. Allied troops referred to the aircraft as “Baka Bombs”.

Made of brass, this item is in EXCELLENT used condition.  There are some very slight scratches due to the age, but there are NO breaks or damage!  The data label is 100% complete, clearly indicating the model, type, and manufacture info.  Some normal marks for being 70+ years old, but otherwise a BEAUTIFUL example.  As this was mounted on a display board, there are traces of rubberized glue on the side (this can be removed).  I have indicated the EXACT location on the Ohka Model 22 in the last photos.  A FANTASTIC addition to any aircraft collection, display, or restoration project!
