D.1 ANNUAL REPORT OF ANNC CPIII-5b
a. CPIII-5b Mechanical Ageing of Rocket Propellants
b. Chief Liaison Personnel
UK: Mr Dave Tucker (Dstl Fort Halstead)
Dr Dave Tod (QinetiQ, Fort Halstead)
NL: Mr Huub Keizers (TNO-PML)
Mr. Gerhard Reeling Brouwer (TNO-PML)
NO: Mr Greger Johansen
c. Reports exchanged
None
d. Meetings/Visits
No formal meetings have taken place in the last year. Discussions on possible (active)
continuation of previous cumulative damage work has been held in the sideline of
other joint NATO activities (AVT-119).
e. Progress/description of activities
NL activity (TNO-PML)
A significant amount of work has been performed on the ageing of solid propellant
rocket motors, using motor analogues. Activities include chemical and mechanical
ageing modelling, sensors, specialised testing techniques, etc. Results of this work
has been discussed with Mr. D. Tucker (DSTL) and Mr. J. Theobold (QinetiQ).
Furthermore work on crack-testing under motor conditions (pressurised) have been
addressed.
f. Future activities
TNO and QinetiQ would like to set-up a joint effort (possibly including Norway), in the
field of life assessment of rocket motors, focussing on cumulative damage of solid
propellant rocket motors. Details and funding are tbd (see item g).
g. Matters of note
Due to personal circumstances the planned meeting on the way-forward has been
delayed a number of times, but both parties still consider this topic very worthwhile
(modelling of cumulative damage and crack growth / crack prediction) for further joint
activities. A meeting is planned for the end of this year to try to define a programme of
work.
The final report of the foregoing activity is waiting for the planned meeting
(Keizers/Tod) to occur.
