Harml Crank Generator -Trip Report
susJECr:
1. General - A trip was made to
DnTE: 29 August 1958
on August , to
monitor work being done on the HG-3 Band Crank Generator.
Present were:
25X1
25X1
2. Power Regulator - A-concentrated effort on the design
of a suitable regulator has~been-made by the contractor since
the receipt of the contract. Anon-dissipative type regulator,
using silicon controlled rectifiers, has-been breadboarded and
has met with general success. A regulator of this type, with .
full wave rectification, would have two silicon controlled
rectifiers,-two saturable reactors, two chokes, a transformer,
a transistor as its mayor components. The contractor believes
that this regulator can be housed in the space allotted in
the generator unit. The important advantage of a regulator of
this type is that it would ioake the efficiency of the unit
independent of crank3.ng speed.
3. Hand Crank --The contractor has me~de a sample hand
crank awl is now running teats, using a magnetic fluid clutch
as a simulated load, to determine the-best type of crank to
be used with the generator. The contractor expects to have a
complete generator unit breadboarded within the next sixty days.
