1. Description of the Project
This project is for continued research and development leading to
a time delay firing device based on the metered flow of a viscous fluid
through a variable orifice.
2. Purpose of the Project
The purpose of this project is to develop a rugged, inexpensive
time delay firing device producing reliable delays in the range from fif-
teen minutes to two months over wide temperature extremes. The need for
a time delay device having these attributes is apparent from considera-
tion of existing Agency delays. Generally, these are of two types: (1)
highly accurate but expensive delays, such as clockworks, (2) cheap but
inaccurate chemical timers that are extremely temperature sensitive.
The proposed delay has an accuracy approaching that of a clock but is
much less expensive to produce and requires less maintenance.
The feasibility of producing reasonably accurate delay times by
extruding a high viscosity fluid through a controlled size orifice has
been demonstrated under Contract RD-88, Task with
Repeated timing tests have shown that this principle is capable
of producing both predictable and reproducible delay times at any given
temperature. A firing mechanism has been designed for the delay.
Although the original design was satisfactory for producing delays
if the operating temperature were known, during the course of its de-
velopment it proved unadaptable for means of temperature compensation.
Toward the conclusion of research a new design was conceived. Because
the task was near expiration, the amount of work which could be alloted
to this new design was limited. However, flow vs. temperature calcula-
tions and limited experiments indicated that with this design the desired
temperature compensation could beechieved.

I+. Support Requirements
There are no support requirements. OtherOdivisions interested 25X1
in the time delay field will be kept informed of the progress of this
project.
5. Total Cost
The total cost for this extension has been estimated at $10,600.00,
including the fixed fee, for an additional seven month period of research.
This cost is considered reasonable.
In the estimation of the project engineer, this work comes within
the scope of the original program initiated with in fiscal year 25X1
1957 as Task J under Contract RD-26. Charges sh fore be made
against Allotment Number 7-2502-10.
