- Did you know that de Havilland also built aircraft ENGINES? In the early days of Aviation, having the right engine was essential; they had to be Powerful, Lightweight and Reliable. At first, like many pioneers, Geoffrey de Havilland built his own engine, called the Iris. Later on, he focused on designing aircraft, and turned to Major Frank Halford for the engines. Frank Halford was an independent consultant on engine design, and a friend of Geoffrey de Havilland since the 1920s. He later became the director of de Havilland Engines. From the 1920s until the late 1950s, the team led by Frank Halford made major contributions in air-cooled propellor engines, and later pioneering work on Jet and Turbojet engines, culminating the mighty Gyron axial-flow jet engine.
This presentation highlights the fact that, thank to Frank Halford and his team, the de Havilland Aircraft company was a leading pioneer in aircraft Engines, as well as airframes.
The Gipsy 31 Piston Engine and H3 Turbo-Prop engines which are on display at the Museum are believed to be the only remaining examples in the world of that model.
This video is based on the interactive "Engine Talk" which we deliver in person at the Museum, mainly on Wednesdays. It is free to anyone who wishes to come along. - วิทยาศาสตร์และเทคโนโลยี
Always like the De Havilland museum videos always very interesting and informative
Excellent presentation, thank you.
The museum is well worth a visit.
Very interesting, I didn't know the museum existed. I'll have to arrange a visit.
I visited your museum 3 days ago. It was a wonderful experience, but I didn't leave long enough for my visit as there was so much to see. Highly recommend a visit to anyone.
Excellent and Very informative presentation.
In 1906 Danish Jacob Ellehammer flew a homebuilt plane, with a Peugeot based 3 cylinder Star-engine on the small island of Lindholm in Denmark. As the island is small he had a pillar with a rope in the center and a concrete track for his plane. But during the coming years he flew his own planes at shows in Europe.
Dennis, thank you for the tour and education! Excellent, if they called me for a review I would give five stars out of five. You only just managed to stave off incandescent anger but you did it perfectly.
Fascinating presentation, love to see a deep dive into each of these engines
Really great thanks!
‘Just another generator’ 😅 a great cross section and description of DH engine evolution.thanks.
Wished I had seen the video before my visit to your fascinating museum, a few months ago. I had a time restriction so I looked at all these engines briefly. I’ll have to come back!
Unbelievably the Gypsy Major is still in operation today in the DHC Chipmunk. It is used in the Battle of Britain Memorial Flight as a tail-wheel trainer and they are in civilian use too.
In 1960 I was an apprentice having spent my final year at the DH Engine Co. Leavesdon with Geoffrey Bell Chambers, their Chief Performance Engineer, whom had taken me under his wing so as to speak. He had a 6L blown open top Bentley and most days he would take me to DH Hatfield where we tested both jet and rocket engines, ie Gyron Junior and Senior, together with the rocket engines Spectre & Sprite. If he was off to somewhere else I would sit on the floor of the daily works van to get there. After finishing said apprenticeship as engine tester I went to sea starting as a junior engineer in the Merchant Navy working on big engines. Totally different of course. My first ship the MV Adelaide Star with twin Doxfords, 2 two stroke super charged direct drive to stern propellers, with each engine developing some 14,000hp.
Great video, thank you!
It was a very cold misty day when i paid my first visit to the museum in 1973ish, i was a volunteer helper , I wandered around looking for someone, then out of the mist emerged a familiar shape, two spinners followed by the nose of a Mosquito WONDERFUL for a 22 year old to see this marvellous aircraft.
One day i shall revisit the museum but live some 200 miles away now.
Its very good to see the engine collection I think St Albans Tech had two gypsy Majors for apprentices to fiddle about with AND the under the guidance of Mr Weller we would run the engines after a strip down and rebuild. Pity about the p1121 another political cancellation.
Very knowledgeable 👍
Very interesting and illuminating. One seems to be stuck with Frank Whittles Jet engine being developed without realiseing that others may have also.
World's first Turboprop.
The Trent was based on an invention by Sir Frank Whittle. It was a RR Derwent Mark II turbojet engine with a cropped impeller (turbine unchanged and a reduction gearbox (designed by A A Rubbra of RR) connected to a five-bladed Rotol propeller. The Trent ran for 633 hours on test before being installed in a Gloster Meteor jet fighter which flew for the first time on 20 September 1945 at the start of a 298-hour flight test programme.
Thank you :)
An interesting video, as always.👍such great engines. We were recently at a fly in in Denmark 🇩🇰,some Chipmunks (former Danish Air Force training planes),,,also seen some Skandinavisk Aero Industri (Kramme & Zeuthen)planes. Those early types also uses de Havilland engines. So we are in the de Havilland craze! 😅🎉. A Tip for interested persons in our region: Visit the Danish Flyvemuseum in Stauning, Danmark 🇩🇰. They have, among other things, some de Havilland planes ( Chipmunk, Tiger Moth,,Hornet Moth) and Kramme Zeuthen planes, every Type ever built. All the best and lookin' forward to come to your Museum sometimes in the future. Greetings from northern Germany 👍🍀🛩️
Fascinating subject.
Awesome video.
Thanks.
Thank you.
Fab ulous presntation and info. The Brits were real innovators and still are.
But did not invent the jet engine or jet aircraft

Yes that's right, Indeed it is without doubt entirely correct that the gas turbine concept was first conceptualised in England before 1800.
It is also correct that the multistage sequential rotor stator axial compressor & axial turbine as used for power generation & propulsion turbomachinery purposes was of course first produced in England by Parsons of Ireland & North England before 1900. The same components as used in all current axial gas turbine aero engines.
Its also well known that serious work on the axial configuration gas turbine aero engine began in England before 1929.
More recently of course the most powerful gas turbine aero engine on the planet in 1944 was in fact the Rolls Royce Nene versions of which would go on to power many jet fighter aircraft including the Mig 15 & & serious UK & US built aircraft during the 1940s & 1950s.
@@Paul-mh9pr The Jet engine was invented in Germany
👍👍👍
👍❤❤❤
Fantastic side of de Havilland that I had no idea about... 1946 turboprop! No idea!
20,000 lbs thrust jet engine... And, powering the Buccaneer!
Just brings back the bad taste of the USA gutting 🇨🇦 aviation, Avro, Canadair, de Havilland....

That last jet fighter project looked promising. Sad that DH and its employees didnt get the chance to develop it and that 20.000 lb thrust engine. British aviation after WW2 seems to be a sad story as a whole.
Britian's aircraft industry was doomed after the countries defeat in WW2.

Of course British military forces did indeed occupy a large part of Germany for decades after 1945.

We are very aware also that it is indeed correct that Russia still posseses a large piece of what was Germany.
The UK & Russia have Nukes.
Germany does not have Nukes.
I gave up half way thru,,all history and no engineering,,
