Another great informative video. As there was no pressure gauge on the emergency blow down bottle, it would be removed and weighed to ensure it still held its gas. On the undercarriage leg the rod that runs from the value at the top around to the gland at the bottom prevents the gland being undone until the pressure is released in the Oleo. What looks like bolts into the body of the Oleo are studs that protrude into the oleo and run in a spline, this keeps the oleo aligned fore and aft. The yellow mark across the tyre and wheel is known as a creep mark, and is a quick visual aid when checking the types, to ensure they have not moved around the wheel on a heavy landing, This could damage the inner tube under the tyre , and possibly damage the inflation valve.
@@mothmagic1 Although on BBMF we were part of the same section, on a bad day when the tyre bay got overloaded, as riggers We used to go over and help. it was common to service the same wheel more than once a day. A new cover on a wheel, put it on the trolly in the morning and pull it apart again later that day with the cover you put on in the morning worn to the cords.
Another great presentation with incredible detail about the workings of the Spitfire. I am amazed at the superb graphics you provide and your well presented explanation of how everything works. Thank you very much for the wealth of detail you show in each video.
Liked and subbed immediately!!! Sorry but I'm already on my third video here. You are amazing with your direct, straightforward explanations. I could watch this all day. Looks like I might.
Thank you for your feedback. I have a lifelong interest in British aviation and in particular, aircraft design. I published two aviation books many years ago and back in 2004 released the first in a series of five unique PC software titles starting with the Lancaster Explored, and followed on with the Spitfire Mk.V, Hurricane, Mosquito and Halifax. Each was of the equivalent to a thousand page book and offered very in-depth coverage of each aircraft. I was immersed in the research and development of these titles for over ten years and have a fascination for how these great aircraft were designed, and how each separate system or item of equipment was incorporated into the complete aircraft. These videos are hard work, but I really enjoy creating new in-depth content that I hope will help to illustrate the incredible work that went into the designs of famous British aircraft. Thanks for watching and I’m posting a video covering the Spitfire Mk.V’s Electrical Installations next week.
Another excellent and most enjoyable video. Can I ask please; when the undercarriage is either fully up or down, and the engine is running, does the hydraulic pump continue to pump fluid through the raise/lower quadrant and the filter back to the reservoir on a continuous loop, or is the pump stopped? Apologies if I have missed something you said about this.
The operation of the Undercarriage Control Unit is illustrated in diagram Fig 3 shown in the video. When the Undercarriage lever is in the gate either at the UP or DOWN end of the U/C quadrant, hydraulic oil from the engine-driven pump enters the control at the "pressure inlet" and passes straight through the "exhaust outlet" back to the reservoir - forming a circuit. In this condition, the system is idling and it is always ready should the pilot operate the Undercarriage lever. The hydraulic pump is engine-driven using the Merlin's camshaft and as such is always working during flight. Thanks for watching.
I'm as in awe of your knowlege as i am thankful that you are doing this! Love it! Really love it!
Thank you so much!

The Lightning used to regularly move the tyre around the wheel if the brakes weren't released promptly when opening up for take off.

Thanks for watching and your great feedback - much appreciated.
Your videos are incredibly good! Flying the Spit is on my bucket list.
Thanks, I'm really pleased you liked it. Yes, would be an incredible experience to be above the clouds sitting behind a Merlin!

Welcome aboard! Thanks for watching and subscribing!
Very nice indeed!
Thank you Jose, glad you liked it.
I teach aircraft tech as part of my job. This is a very high quality presentation. Do you have a technical background?

@@ukaircraftexplored6556 Thanks - that makes sense. I wonder if the u/c quadrant gets hot during the course of a flight....
Sorry can i ask the landing gear is mounted to the wing main spar or the centre plane wing spar? Thank you
Thanks you can find everything the internet
I watched this so i could build it in a game
fank you
You're welcome
