Impressed with your work sir, I can vaguely remember just how fiddly that was  :unsure:

Quote from: zenrat on August 19, 2023, 03:47:48 AMI'm pondering some sort of Dieselpunk (or is it Keropunk?) 'chute powered ejector seat.


All RFC/RAF got parachutes or just James Bigglesworth esq. ?  :angel:

Well this is The Professor's prototype, so just this one.
I'm thinking about a seat mounted to rails attached to the upper wing.  A packed chute is mounted on the upper wing which when opened drags the seat out of the nacelle up the rails and away.

An elegantly Kerbal Space Program-esque solution.

But will the parachute pack say ACME?

I can't help thinking that some hefty elastic bands should be involved somewhere................  ;D
Kit's Rule 1 ) Any aircraft can be improved by fitting longer wings, and/or a longer fuselage
Kit's Rule 2) The backstory can always be changed to suit the model

...and I'm not a closeted 'Take That' fan, I'm a REAL fan! :)

I'm assuming the parachute will be a re-purposed 'chute from an observation dirigible? :unsure:

Right again, Kit! A very early collaboration between Messers Martin and Baker.    The M&B spring-loaded elastic whoopee cushion!  The prototype model was constructed, or so it is believed, from Valentine Baker's grandfather's "Everite" braces (one source claims that the elastic from Baker's grandmother's underwear was used)  and a  large second hand bedspring  from a redundant mattress..

When the ejector pin was withdrawn, the combined power of the compressed spring and elastic in tension hurled the intrepid aviator  violently upwards  along the seat rails, over the upper wing  and out to the left (thus avoiding the  propellor  of the DH2)  whilst a further  long elastic band pulled the ripcord  on the parachute pack when the ejected individual was a reasonable distance from the stricken machine.  Manufacture was sub-contracted to the Aeroplane  Construction and Maintenance Establishment at Farnborough...............hence the letters A C M E  stencilled on every installation.  Pilots were told that if the aeroplane was in terminal difficulties,  "pull the pin and twang out to safety"

Other members of the group will (I hope) add further information on this unique piece of kit.

Sounds a bit like the mechanism in Billy Connolly's Jobbie Weecha  ;D

Hmmm, yes.
Very good technical description Rheged.
:thumbsup:

Having removed the jigs and offered up the engine I realised the main mounting point for it could be a pin fitted between a hole drilled in the back of the engine and the original rotary motors boss which is moulded on the back of the firewall.  This means that the engine subframe doesn't have to actually mount the engine securely, just look like it does.
This is a good thing.

Can I ask where the jet's air intake is ? Or does it come in between the pilots legs ? Curry night in  the Mess Thursday's ?  :angel:

No rockets involved in the ejection system?

The ring just forward of the wing strut, with lots of "V" shaped supports & simulated mesh, is where the air enters the engine, the front is made up of sundry systems drawing power from the turbine shaft.
