Hi,
I’ve just received a copy of some Demon turret trials that were carried out in 1937. One of the trials was to test the intercommunication slip rings.
Does anyone know what these are/were? All the report says is:
Satisfactory functionaing of the inter-communication slip rings and reflector sight lamp was obtained under all conditions in the air and whilst the turret was being rotated. The slip rings are in a rather exposed position and become covered in oil from the turret. Only a duralium door in the bottom of the fuselage protects them from dust and dirt.
Also if the gunner was operating the machine gun how did he rotate the turret? Was it by feet pedals or pressure pads next to his knees?

“Slip rings” are a standard “Electrical” term used in motors and other rotating electrical equipment to describe two sets of rings that allow fixed contacts to maintain contact with the rotating section to maintain an electrical circuit, they usually run around the pivot point so as to maintain contact regardless of the position of rotation, in this case the slip rings were obviously related to intercom wiring rather than electrical power, but if you google “slip rings” and “motors” you will probably find drawings and text to provide more general descriptions.

The ‘Lobster Back’ FN1 turret fitted to some Demons had control handles, a bit like bicycle handles, which controlled the movement of the turret and firing of the gun.
