1. Project Description:
The HG-100 is a tactical handcranked generator to be used in the
operation of field portable electronic equipment and the charging of
batteries. The unit is to supply 75 watts of average and 150 watts of
peak power at 12 volts. The design goal is for a 10 pound package of
230 cubic inches.

7. ProjectStatus:
On a test stand with dummy loads, the HG-100 prototype has suc-
cessfully met all of its electrical specifications. My purpose on this
visit was to test the HG-100 with its intended load, the RS-100 radio
set. I operated the HG-100 both on the ground and on a tree. Either
technique is suitable but the tree adds much stability and eases the
cranking effort considerably. There appears to be no loads or duty
cycles demanded by the RS-100 that the HG-100 cannot provide. Unfor-
tunately, before the cranking dynamics could be experimented with in
greater detail, we had a catastrophic failure in the RS-100. The
failure is believed to be in one of the transmitter output stages
since it occurred after the antenna was accidentally shorted. Testing
was continued with dummy loads. Efficiencies as high as 63 percent
are possible with the HG-100 making it one of the most efficient hand
generators ever constructed.
The GN-54 was also available for inspec-
tion so I had a chance to compare i with our unit. The HG-100 was
originally a modified GN-54. The following is a comparison of a few of
the major design.features:

Both units are designed for tactical field use and are capable of meeting
the necessary environmental specifications.
The first HG-100 units are scheduled for delivery during the first
week of October. The project is approximately 85 percent complete.
