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 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.

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.

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.

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.

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.

@@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.

@@DoktorBayerischeMotorenWerke It is of course obviously very important to note that factually speaking the following info is indeed 100% factually correct. *_Kharzeestan Krappenz DiktorBummer Jurkzxoffenz etc and co - they should all note well with great awe & much reverence._* Maximinime's engine was essentially a turbocharged boiler feeding a hybrid steam / boiler combuster exhaust powered turbine based on Parson's turbomachinery inventions, driving a compressor producing enough power for a lawnmower. 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. The TG-100A which led to the j35 etc benefited from the Anglo/American technology exchange with one of its designers, Glenn Warren, stating that one of the most important British contributions was the concept of multiple combustion cans. *We can clearly see that Centrifugal compressor gas turbine aero engines are currently produced.* *_In 1944 the centrifugal compressor RR Nene engine was of course the most powerful & most reliable gas turbine aero engine on the planet. Versions of the Engine would of course be produced in the US for use in US built jet fighters for the next 10 years & of course it was built in Russia for Mig 15 & Mig 19 aircraft._* Whittle was the first to conceptualise & patent a number of versions of the gas turbine aero engine including axial compressor, centrifugal compressor, reheat & turboprop & various types of turbofan arrangements. Whittle was the first to demonstrate the basic Whittle pure gas turbine aero engine in 1937 of course. *The Pratt & Whitney PW-200 range of engines for example are a Whittle engine including reverse flow combusters of course, they are also a version of all current internal combustion gas turbine aero engines, differences being compressor type, combuster configuration & fan configuration.* _The gas turbine was of course invented before 1800 in England. Work on axial compressor turbojet engines began in England before 1930._ *_The world's first multi stage sequential rotor stator bladed axial turbine & axial compressor having of course been first produced in England around or before 1900. Of course it is factually entirely correct that the same basic axial turbine & axial compressor technology for example is used in both Rankine & Brayton cycle turbomachinery._* *It is factually indisputable that C A Parsons manufactured the world's first axial turbine power generation turbomachinery machinery & axial turbine ship propulsion turbomachinery before 1900.* _The exceptional & excellent W & J Galloway & Sons of course would be a good example of a company making steam engines & their boilers at the time during the late 1800s the world's first steam engines of course having been constructed in England in previous centuries, steam engines are not axial turbine power generation turbomachinery utilising axial turbine gas turbine & axial compressor technology in power generation & propulsion machinery, W & J Galloway & Sons did not involve themselves with axial turbines or axial compressors. A steam engine is of course a piston engine. The world's first steam engines being of course produced in England before 1800._ *The axial multi stage sequential rotor stator turbine of course exists in its own right independently where ever & how ever it is utilised including when used as a Dehavilland, Halford, Metrovik, Armstrong Siddeley, Bristol, Power Jets or Rolls Royce Gas turbine aero engine or ship propulsion gas turbine or for example a cruise missile engine or as power generation turbomachinery using Brayton or Rankine cycle turbomachinery configurations.* _The said axial turbine being produced for the first time in the world in England before 1900._ *_There is of course no doubt that the world's first basic axial compressor jet engine arrangement was manufactured in England before 1937 work having started before 1930._* *It is factually correct that there are currently no instances of jet aircraft powered by Jumo engines or German technology engines, no US aircraft were powered by German jet engine technology. Such ridiculously shoddy extremely short life engines with sheet steel combusters & turbine blades would not under any circumstances have achieved US or UK certification* The Nickel super alloys which are primarily high Nickel content & low iron content were developed around 1940 in Hereford England for turbine blade use in internal combustion gas turbine aero engines. At the time they were available nowhere else. Germany & the US would attempt to use stainless steels, mostly iron with high nickel or chrome content, the US GE turbocharger division of course didn't need anything better for piston engine turbochargers for example. Germany had plenty of Nickel but hadn't figured out the why & how of Nickel super alloys. *_Of course All 1940s & 1950s US & UK, Russian, French / other countries built jet aircraft using technology from the UK based on the early Whittle engines & work done at the RAE & Metrovik up to 1943._* Indeed there is no doubt that all failed German attempts were of course half soaked copies of UK technology using partial info obtained from UK industry & academia. *_Rolls Royce of England & England's Shires & Lands now has 2 wholly owned subsidiaries in Germany one of which handles routine work on smaller 2 shaft engines & a wholly owned subsidiary in the US that was previously Allison of course._* *C H E E R S* & *Toodle* *-PIP-* *_Old_* *CHAPs* 😎👍 . .... ... . ... xcxcvcxbc . ..... ......... izivvvvicxc

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.

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....
