Abstract:

A means for testing the accuracy of a bombsight without dropping bombs is provided by photographing the test airplane from the ground with a special vertical phototheodolite. The design of the phototheodolite employs a standard 16 mm movie camera which photographs through a set of wire cross hairs held vertically above the camera. In analyzing the results azimuth errors are measured directly on the enlarged 16 mm frame while range errors are computed from the reading of a clock which is photographed along with the airplane and cross hairs. The accuracy of the vertical phototheodolite is indicated by errors in azimuth of not more than .75 mils and errors in range of about five feet plus .75 mils for an airplane moving at 180 miles per hour.
