Having recently visited Duxford I swear every time I hear the engine start on these videos I can smell the distinctive aroma ! Another great video where I have learnt something new , many thanks for putting these together.

What an amazing series of detailed information told in a logical and easy to follow format. Thanks! Feel like I could hold my own in a Spit.

A gentleman I know who flew the Mark V in 1944 told me how they would find the Rotol propellors of their squadron aircraft “swapped” with the inferior De Havilland type which equipped the aircraft of a fellow squadron in their wing. Suffice to say, it didn’t please the pilots in his squadron very much!

@ukaircraftexplored6556 3 года назад

Interesting. Thanks for watching

"Leading edge technology". 👍🙂 Very appropriate! 1:30

brilliant video again. I look forward to your treatment of the Lancaster!

Brilliant detailed set of videos. I am still however confused as to when and why one would use the throttle lever and or the airscrew lever? I'm a glider pilot not a power pilot but still interested. A simple explanation would be really helpfull. Thanks

@ukaircraftexplored6556 2 года назад

With the introduction of Propeller variable pitch units, the airscrew control lever was used by the pilot to select the pitch required by either moving the lever fully back fine for the D H Propeller or fully forward for the Rotol propeller.

I believe early Mk Vs built at the CBAF used the earlier 10'9" variant of the Rotol (with corresponding rounded, blunt spinner) as used by the Mk IIA, before moving to the 10'3" Jablo type with broad root and pointed spinner?

@ukaircraftexplored6556 2 года назад

Thanks for info

@jadams3427 2 года назад

Brilliant presentation. Thanks ! I am looking for any info on the spinner for a 3 blade Hydromatic installation on a Spitfire. I would like to scan and CAD model the whole thing.

@ukaircraftexplored6556 2 года назад

Glad it was helpful and thanks for watching.

@jeffreylebowski4927 Год назад

Thank you very much, I enjoyed your explainations alot, however I have a question, - if the propeller rpm causes the blades pitch to change due to centrifugal forces opening a valve to allow oil to push a cylinder, then how does the "airscrew control" lever in the cockpit work? Does it just increase the propellors pitch or does it set the blades range of pitch lower while reducing throttle or what is happening and how? Thank you very much.

The Airscrew Control Lever for the de Havilland 20° or Rotol 35° constant speed airscrew is fitted on the throttle quadrant. The de Havilland 20° airscrew has a Positive Coarse Pitch position which is obtained in the extreme aft position of the control lever, when the airscrew blades are held at their maximum coarse pitch angles and the airscrew functions as a fixed airscrew. Some aircraft are fitted with a De Havilland hydromatic propellor. Thanks for watching.

@wilf609 3 года назад

Were they interchangeable? Any performance difference between them? Very interesting video.

@ukaircraftexplored6556 3 года назад

Yes, they fitted to the same No. 5 Engine Shaft. Thanks for watching

@wkelly3053 Год назад

Great presentation. So, the ROTOL pitch range is 30 to 64 and the de Havilland range is 34 to 54. That seems like quite a difference, especially toward the course range for the ROTOL. Was the ROTOL propeller able to be used effectively on higher power engines than the de Havilland? The ROTOL blades also looks like they are of greater surface area than the de Havilland blades, at least to my eye.

The info in the video is all I have at the moment. Thanks for watching
