Back Bristol Type 191/192 "Belvedere"

Bristol Type 191/192 "Belvedere"

The Bristol 173 was the first helicopter specifically designed for commercial operation and passenger transport in particular. The first prototype, which flew on 3 January 1952, was powered by two 520hp Alvis Leonides engines and could carry ten passengers. The tandem rotors were identical to those of the Bristol 171 "Sycamore". Trials were carried out with this aircraft in 1953, from the aircraft carrier HMS Eagle. The second prototype was similar to the first but was modified to test the characteristics and effects of two stub wings and later a four-bladed rotor. The Bristol 173 Mk.3, of which three were built, with capacity increased to 16 seats and Alvis Leonides Major engines, was offered to BEA.

Unfortunately, none of these aircraft succeeded in overcoming a series of developmental problems and subsequent projects undertaken by Bristol — models 191 and 193 — in response to Royal Navy and Canadian naval specifications were no more successful. However the Type 192, the prototype of which flew on 5 July 1958, was adopted by the RAF. In the initial configuration, this aircraft had a purely manual system of control and wooden rotor blades but power controls and metal blades were standardized on the fifth prototype built in 1960. That year, three pre-production aircraft were assigned to the RAF for a series of trials for which they were based at Odiham. Twenty-six of these helicopters, called the "Belvedere", were ordered and used for some years for military transport, not only in the United Kingdom, but also in the Middle and Far East. The "Belvedere" was withdrawn from service in March 1969.

The production Bristol 192s had an all-metal, skinned fuselage and an anhedral tailplane, compared with the dihedral one of the Type 173. The two rotors had four metal blades and the front wheels of the fixed quadricycle landing gear were self-castoring. The helicopter's maximum capacity was 30 seats or 2700kg internal payload. The instrumentation also permitted night flying.

In July 1958 the Bristol 192 made its maiden flight and this marked the successful climax to the development of the 173. As the Westland Belvedere this entered service with the Royal Air Force, though this was only after the 191 and 193 had been cancelled by the RAF and Royal Canadian Air Force respectively. The 192 was powered by two Napier Gazelle Series 2 engines derated to 920shp.

As the 192C it was tested by BEA and offered its 24 passengers a unique high-speed service between London and Paris.

On May 30, 1961, C T D Hosegood flew from London to Paris in 1 hour 41 min 28 sec and on June 2, 1961, from Paris to London in 1 hour 40 mm 55 sec. This is the equivalent of 202.32km/h outwards and 203.51 km/h on the return flight.

Bill Gunston "The Illustrated Encyclopedia of Commercial Aircraft", 1980

Bristol Type 191/192 "Belvedere"


- The first Belvedere suffered noise and stability problems - rectified by redesigning the rotor hubs and tailplane.

- On 24 August 1952 the prototype for the Belvedere series made its maiden flight.

- The prototype was demonstrated at the Farnborough air show in September 1952.

- British European Airways leased a Belvedere briefly but never used it in commercial service.

- The first production aircraft with Gazelte engines made its initial flight in July 1958.

- The Belvedere had a long career, ending its RAF service in March 1969.

I was on last Manufactures Course ,at a place Called Old Mixan went on to serve on the Beleverderes at at RAF Seletar on (Helecopter Engineering flight), as a Airframe fitter. until the end of the Belverdere, and then went to Changi working on the whirlwinds also in HEF. Fond memories of Singapore. I lived at Seleter Hills Estate. I once flew up country when one A /C hit over head power lines, we fixed it situated on a nice beach, changed the front Blades and Gearbox.

I was posted to RAF Odiham 72 Sqn in mid 1962 after training.A very sad time as a belvedere had crashed coming back from an exercise in Germany with no survivors some ground crew also on board.Soon learnt about the belvedere and enjoyed my posting,which included some "aircrew"time as most trained up aircrew were sent out to Borneo.New "choppers" were quickly serviced /tested then again sent to Borneo.With a short break on Vulcans,posted to Singapore(66sqn)in late 65.Did line servicing and "inflight blade tracking"that made a change.Moved into the hangar on 2nd line servicing with promotion.Stayed there until Feb 68(posted home)one belvedere had become a "Christmas tree"the writing on the wall"very sad.

i was at the filton air display in 1956 when a twin rotor helicopter crashed
i had a very clear view of the crash which was due to it taking of behind a heavy cargo plane and its associated turbulence not in my view due to pilot or the aircraft

Bill Newton, e-mail, 15.01.2017reply

I did the blade tracking course at Odiham and went to Singapore during confrontation. I am writing a small piece about my experiences in Seletar and Borneo. I made some good friends and thought the aircraft was a masterpiece of design and only spoilt by MOD lack of commitment.

I was one of the first members on the BTU at Odiham. I have
read many comments on the Belvedere but i wonder in 1961 we
did an attachment to the USAF Station, Weathersfield nr Stansted,we were engaged onflying dignatorys during the CND demos. The yanks looked after us all quite wee.Good attachment

I wonder if anyone can help me with the Serial No of a Belvedere that was carried on passage on the Deck of HMS EAGLE, I served on the EAGLE 1964 to 1966, it would be during this time. Sorry for being so vague, I have managed to record the Serial Nos of all the other Aircraft on board during my time on her, I am only too happy to help anyone who requires any info during this time period.

I was a member of the design team under Raoul Hafner at Bristol Helicopters. People confuse the Type 173 and Type 192, Belvedere. The Belvedere was of almost twice the 10,000lb All Up Weight of the 173. The 173 was scheduled to have 2 Bristol Janus, 800 bhp engines but UK government stopped their development. With the temporary installation of two Alvis Leonides piston engines of only 550 bhp, the aircraft was underpowered and so, understandably, BEA cancelled their order for them.
The Belvedere was initially designed to use a Rover Neptune APU to start the engines and run ground services but the government again interfered and insisted, much against our advice, on our using the Av Pin starters for the 1,650 shp Napier Gazelles. It was these which caused the explosions which caused the two crashes of the Belvederes and loss of life. Sadly inept interference by technology-ignorant government officials finally killed off the British Industry and resulted in so many of our experienced aircraft people joining USA, French and German companies from whom we now import our aircraft!

Hello Reg, I have just come across this site. It made my day to hear from some one from the past. I hope you are keeping well, the last time we meet was I think at Jack Boffey funeral.Seeing your name brings back many happy and not such happy memories. I still remember Raul Hafener standing on a desk in the design office, saying we could look forward to the sky in Weston being black with Helicopters then Westlands took over and the site at Weston became a satellite site.

During an exercise in Malaysia in 1966-67, Belvederes were tasked to move Landrovers and guns of 'A' Field Battery, RAA. One of these Belvederes had an engine blow up (literally, quite a loud bang). I was doing air traffic control liaison at the time and heard the pilot say "We've lost an engine, have to drop the load", and he released the underslung Landrover which pancaked from about 200 feet onto a flat piece of ground. The Belvedere landed safely, but the Landrover was flattened down to about 2 feet high. Wheels were horizontal, radio batteries were through the floor, radios were through the top of the batteries, not much was salvageable. We told the driver it was a "Member To Pay" event as he was responsible for the Landrover. Wish I could have recorded his response.

I am gathering material for a book on the Belvedere HC1 helicopter. I would like to hear from anyone who flew or maintained these helicopters in the field. Any help would be appreciated.

David Hardiman, e-mail, 10.02.2021 Alex Crawford

Did you ever finish the Belvedere book?
If so can you send me details please.
I worked on them for two years in Aden, Singapore and Borneo 1964 to 1966



John Edwards, e-mail, 30.08.2010reply

I can go back a little further than you service men.
I first met the Belvedere when it was still a pile of parts on the bench in Westlands at Weston super Mare.
My first task, together with my companion fitter, was to construct the most complex piece, known as station 0, that was the main mounting for the front undercarriage and the nose joint.
It took a few months and numerous trips to the drawing office but as it was the prototype thats not surprising.
I went on to do lots of different parts including I put the floor in every single one of the 26 aircraft thats a lot of rivets.
I moved then to the development department and built the first pilots bubble door, I dont think it was put into production though.
I went on loan to EDL (Electronics Development Laboratory) and built there the slip rings which were mounted on the rotor head for rotor blade strain gauge work and I also mounted instrumentation on the hydraulic jacks in the flying controls to monitor valve movement.
When I joined EDL permanently I balanced all the Rotor synchronizing prop shafts,
Spent many hours watching over the flying controls fatigue rig and doing calibration runs on de-icing jets for rotor blades
The Belvedere was known in the workshops as the Bevelgear
