De Havilland Comet
« on: March 13, 2015, 08:56:10 AM »



I think it would be very cool to have the first commercial jet-liner in IL2. There aren't many transport planes in IL2, and when there are, they are mostly two-engine propeller similar to the DC-3. Also, as far as I know, there isn't a single jet airliner plane that has been made for il2: This would be a great first jet airliner for the sim.

The de Havilland DH 106 Comet was the first production commercial jetliner. Developed and manufactured by de Havilland at its Hatfield Aerodrome, Hertfordshire, United Kingdom headquarters, the Comet 1 prototype first flew on 27 July 1949. It featured an aerodynamically clean design with four de Havilland Ghost turbojet engines buried in the wings, a pressurised fuselage, and large square windows. For the era, it offered a relatively quiet, comfortable passenger cabin and showed signs of being a commercial success at its 1952 debut.

Comet 1

The square-windowed Comet 1 was the first model produced, a total of 12 aircraft in service and test. Following closely the design features of the two prototypes, the only noticeable change was the adoption of four-wheel bogie main undercarriage units, replacing the single main wheels. Four Ghost 50 Mk 1 engines were fitted (later replaced by more powerful Ghost DGT3 series engines). The span was 115 ft (35.05 m), and overall length 93 ft (28.35 m); the maximum takeoff weight was over 105,000 lb (47.628 kg) and over 40 passengers could be carried.

Comet 2

The Comet 2 had a slightly larger wing, higher fuel capacity and more powerful Rolls-Royce Avon engines, which all improved the aircraft's range and performance;[148] its fuselage was 3 ft 1 in (0.94 m) longer than the Comet 1's. Design changes had been made to make the aircraft more suitable for transatlantic operations.[148] Following the Comet 1 disasters, these models were rebuilt with heavier gauge skin and rounded windows, and the Avon engines featuring larger air intakes and outward-curving jet tailpipes. A total of 12 of the 44-seat Comet 2s were ordered by BOAC for the South Atlantic route.[151] The first production aircraft (G-AMXA) flew on 27 August 1953. Although these aircraft performed well on test flights on the South Atlantic, their range was still not suitable for the North Atlantic. All but four Comet 2s were allocated to the RAF with deliveries beginning in 1955. Modifications to the interiors allowed the Comet 2s to be used in a number of different roles. For VIP transport, the seating and accommodations were altered while provisions for carrying medical equipment including iron lungs were incorporated. Specialised ELINT and electronic surveillance capability was later added to some airframes.[153]


Comet 3

The Comet 3, which flew for the first time on 19 July 1954, was a Comet 2 lengthened by 15 ft 5 in (4.70 m) and powered by Avon M502 engines developing 10,000 lbf (44 kN). The variant added wing pinion tanks, and offered greater capacity and range. The Comet 3 was destined to remain a development series since it did not incorporate the fuselage-strengthening modifications of the later series aircraft, and was not able to be fully pressurised. Only two Comet 3s began construction with G-ANLO, the only airworthy Comet 3, demonstrated at the Farnborough SBAC Show in September 1954. The other Comet 3 airframe was not completed to production standard and was used primarily for ground-based structural and technology testing during development of the similarly sized Comet 4. Nine additional Comet 3 airframes were not completed and their construction was abandoned at Hatfield. In BOAC colours, G-ANLO was flown by John Cunningham in a marathon round-the-world promotional tour in December 1955.[156] As a flying testbed, it was later modified with Avon RA29 engines fitted, as well as replacing the original long-span wings with reduced span wings as the Comet 3B and demonstrated in British European Airways (BEA) livery at the Farnborough Airshow in September 1958.[157] Assigned in 1961 to the Blind Landing Experimental Unit (BLEU) at RAE Bedford, the final testbed role played by G–ANLO was in automatic landing system experiments. When retired in 1973, the airframe was used for foam arrester trials before the fuselage was salvaged at BAE Woodford, to serve as the mock-up for the Nimrod.

Comet 4

The Comet 4 was a further improvement on the stretched Comet 3 with even greater fuel capacity. The design had progressed significantly from the original Comet 1, growing by 18 ft 6 in (5.64 m) and typically seating 74 to 81 passengers compared to the Comet 1's 36 to 44 (119 passengers could be accommodated in a special charter seating package in the later 4C series). The Comet 4 was considered the definitive series, having a longer range, higher cruising speed and higher maximum takeoff weight. These improvements were possible largely because of Avon engines with twice the thrust of the Comet 1's Ghosts.[126] Deliveries to BOAC began on 30 September 1958 with two 48-seat aircraft, which were used to initiate the first scheduled transatlantic services.

I'm just a sucker for civilian aircraft.

I love IL2's engine, and I love flying civilian planes around. I have almost every single civilian aircraft on here downloaded, but there's a distinct lack of jet liners :^< A man can dream

This plane is, to my opinion, one of the most important of all, a step forward in civilian aviation just as the Me-262 was a few years before in military aviation.

GJE52, you do know that that isn't a Comet right? That is the Hawker Siddeley Nimrod.....I know terrible name right? The Nimrod was a extensively modified development of the Comet

As far as I know you're right.
Come to think of it... there isn't a single manned space system that has been made for il2, and IIRC no Gobbler's Knob either.
Time for another request?

Mike, but in jet age, it is quite ussual to scramble towards passanger aircraft... or that in interception area is apart from target some other plane (civilian). <--- that is why I am doing the Tu-104

Oh yes... I already see someone doing a KAL 007 mission.
Hint: Please don't. Thanks ;)
