| A 17.5-foot long multi-conical taper which connects circular waveguides of 2.25 in. and 29.7 in. in diameter was fabricated and evaluated at X-band. The taper and 8 sections of 29.7 in. D circular waveguide were fabricated using thin sheet aluminum, rolled, and longitudinally welded. Conceptual design studies were carried out for 29.7 in.

|
| Results are presented from an investigation of the load distribution to the main bearing of the AN/FPS-24 radar under actual operating conditions. The bearing is a 10-foot diameter 4-point contact being subjected to thrust, radial, and overturning loads. Load determination was made by instrumenting one of the bearing balls to measure its deformation due to load. The results are inconclusive due to problems of mechanical interference incurred during testing; however, ... |

Raymond D. Arnold; GENERAL ELECTRIC CO SYRACUSE NY HEAVY MILITARY ELECTRONIC SYSTEMS
|
| The Man-Pack Radar Program was undertaken to develop a lightweight highly transportable aircraft search radar. The General Electric radar is one of three such radars, having been selected for its simplicity of design and operation. This radar did not live up to expectations as a search radar, having fallen short of the range requirements and showing a tendency to be unreliable. Following the redirection of the project, the radar was ... |
