| Fieseler Fi103R |
By mid-1944, the Fi-103
(V-1) had been deployed to special units in Germany and in the occupied
countries for attacks against the British Isles. It was a simple weapon, a streamlined
airframe carrying an explosive warhead on which an Argus AS-109 pulsejet was
mounted. The pulsejet was equally simple; a tube lacking both turbine and
compressors into which vaporized fuel was injected in spurts and ignited.
Shutters at the front of the tube opened to admit air during the intake phase
and closed during the ignition phase to direct the combustion gases to the
rear. It had very few moving parts, was simple to make and easy to maintain.
