Description
These motors are designed as propulsion units for 60 kilogram ordinary or land use bombs. The motors are used to propel these bombs from crude V shaped wooden troughs for land bombardment. The motors are interchangeable and may be used on either the 60 kilogram ordinary or land use bomb.
The propellant charge consists of three sticks of 343 DT2 and 343 special DT2 (code designation) for the Model 10 and type 3, respectively. The chemical analysis of 343 DT2 is 65 percent nitrocellulose, 30 percent nitroglycerine, 3.0 percent ethyl centralite and 2.0 percent sodium chloride. The chemical analysis of 343 special DT2 is not known but probably involves a small variation of 343 DT2. The complete Japanese designation for 343 DT2 is type 93 Mk 2 propellant.
Ignition: The propellant is ignited by an electrical squib. Current is supplied by a hand generator.
Launcher: A crude V-shaped wooden trough mounted on a bipod forward and a steel base plate aft. The angle of elevation can be varied.
The variation in the size of the two motors is possibly a means of varying the range.
