display at rallies. There are legitimate stationary engine applications for
them and there are an improbable number about for reasonable money - you
can pick up a running Rover fire pump for about the same as an unrestored
Amanco or Bradford open crank. The easy path is to ban them like gazebos at
Astle Park, but I feel it is unreasonable to do so when sensible measures
can be applied to make them safe.
I am fully seized of the dangers inherent in running an engine of unknown
provenance that rotates at perhaps 20,000RPM. Blades making a break for
freedom through the case are the real danger and even in aircraft
applications where the engine case is armoured, they are still known to
enter the fuselage on rare occasions. Just imagine the carnage if an
unshielded turbine broke up, spraying red hot blades about the place. That
said, there is little likelihood of engines on display being run up to
maximum RPM, so the actual danger is ameliorated to an extent.
I'd be prepared to correlate advice and suggestions into something for SEM
and I'm aware that this forum has a number of contributors who have spent a
lot of years around gas turbines. What do you think could be reasonably
achieved in order to make these interesting devices safe for public viewing?
