A project to make a non-flying model Helicopter powered with a steam engine with a flash boiler
This has been an ongoing project with very little time spent on it - I reassembled the heli to make this video clip and ran the engine on compressed air for ease.
The engine is a single cylinder double action wobbler and will turn the rotors at 10psi and has a suprising amount of torque on start up. I have not had the pressure above 25psi with the rotors engaged but the engine has been tested at 90psi.
"LBSC" was the pen-name of one of model engineering's most prolific writers. Lillian "Curly" Lawrence was born in 1882 and died in 1967.
Ayesha (The name Ayesha comes from a character in "She", a novel by H. Rider Haggard) is one of the more famous model locomotives by LBSC and was used in a challenge to prove that the 2 1/2" scale Live Steam Locomotives where capable of pulling human passengers. LBSC designed a boiler for his model and set out to prove the point.
