Hutchinson, Robert (2003) Weapons of Mass Destruction: George Weidenfeld & Nicholson, ISBN 0297830910 Japanese developments In 1943, an Argus pulsejet engine was shipped to Japan by German submarine.
La-9 derivatives included examples fitted with two underwing auxiliary pulsejet engines (the La-9RD) and a similarly mounted pair of auxiliary ramjet engines (the La-138); however, neither of these entered service.
This was necessary to avoid damaging the mother craft's fuselage and tail surfaces when the pulsejet ignited, as well as to ensure a "clean" airflow for the Argus motor's intake.
Beginning in January 1941, the V-1's pulsejet engine was also tested on a variety of craft, including automobilessfn and an experimental attack boat known as the "Tornado".
The pulsejet, internal systems and warhead of the missile were removed, leaving only the wings and basic fuselage, now containing a single large fuel tank.
The simple, Argus-built pulsejet engine pulsed 50 times per second,sfn and the characteristic buzzing sound gave rise to the colloquial names "buzz bomb" or " doodlebug " (a common name for a wide variety of flying insects).
