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.
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.

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.
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.
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 👍🍀🛩️
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.
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.
by 1960 de Havilland became part of Hawker Siddeley Group, an amalgamation which included Gloster, Blackburn, Hawker, Avro and Folland aircraft companies, in 1977 with a merger of the rival BAC Group this became British Aerospace (or BAE Systems today). edit: de Havilland Canada still exists today manufacturing aircraft.
@@DoktorBayerischeMotorenWerke 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.

Ohain was copying Whittle but used a never to be used again radial inflow turbine (to avoid patent conflict) which first ran after Whittle's world's first demonstration of a prototype pure internal combustion gas turbine aero engine in 1937. The turbojets used for the Bow-wing ( see B-47 wing folding incidents) were of course based on the Metrovik UK f2/3 gas turbine aero engine work which first ran in 1943, was flight certified but not required at the time, development of more powerful engines continued.
