Flying the Do 217 M-1

In October 1945 British Captain Eric Brown undertook full handling trials with a Do 217 M-1 WNr 56158 at RAF Farnborough. He recalled a distinctly "underwhelming" experience. Brown recalled that he took off with full power of some 2,700 rpm and the lightly loaded Do 217M left the runway at 160 km/h (99 mph). Brown held a shallow climb, waiting to reach 200 km/h (120 mph) before retracting the undercarriage. Brown timed the time it took to retract, which was between 30 and 40 seconds. At 150 m (490 ft) he reduced power to 2,500 rpm and raised the flaps at about 230 km/h (140 mph). With the flaps up a climbing speed of 230 km/h (140 mph) was established giving a rate of "very moderate proportions".

While in cruising mode, Brown took the Dornier to 5,500 m (18,000 ft) and with the tail at +2 degrees angle of incidence, gave it a top speed of 523 km/h (325 mph), true air speed. Brown stated the aircraft was very stable about all three axes, and the controls were well harmonised and effective, and not unduly heavy for bomber operations. At the other end of the speed range, stall occurred at 154 km/h (96 mph), and was characterised by a gentle nose-down pitch. At this stage Brown tried the Dornier's single-engine performance and this "proved decidedly unimpressive". It underlined that the aircraft was underpowered. Above 1,500 m (4,900 ft), height could not be maintained at 2,300 rpm and its ceiling was barely 7,600 m (24,900 ft). Brown reverted to "normal power", and decided to "chance his arm" (risk) on a dive-bombing procedure in what he described as a "ponderous aeroplane". Brown made a straight dive to 700 km/h (430 mph), the maximum permitted below 3,000 m (9,800 ft) in order to get a feel for the controls, which began to stiffen considerably. The engine revolutions built to 2,750 during the dive causing a lot of noise. Brown pulled the aircraft out of its dive though it called for a "good full-blooded heave" on the control column.

After climbing to regain the height lost, Brown decided to test the tail-mounted, clamshell-like dive brake and automatic pull-out equipment. The Dornier entered the dive automatically when the dive switch was selected and soon attained its "braked condition", limiting the airspeed to 575 km/h (357 mph). The pull-out was initiated by hitting the bomb-release stick on the control column or selecting the "level flight" switch, which also retracted the dive-brake. Brown stated, "All very sedate and totally unimpressive as a precision weapon".

The landing procedure began at an air speed of 250 km/h (160 mph). The oil coolers were opened fully and the radiator hatches opened to 30 degrees. At 240 km/h (150 mph) the undercarriage was lowered, which again took 30 to 40 seconds. Flaps were lowered to their start position at 235 km/h (146 mph) and fully deployed at 220 km/h (140 mph). The tail had to be trimmed to 4 degrees incidence (tail heavy). Final approach was made at 200 km/h (120 mph) and touchdown occurred at about 160 km/h (99 mph). Landing weight was roughly 13,000 kg (29,000 lb). The control column had to be held back beyond the neutral to keep the tail wheel locked until the landing run was complete.

Pros and cons

Pros:

• Good payload (up to 4 x 1,000 kg)
• Quite fast and manoeuvrable for a bomber
• Can perform as both a level and dive bomber
• Very easy to fly and to land
• One of the bombers that can demolish a base (AB) or all three bases (RB/SB) with a single run
• Can be very difficult to catch once it reaches a high altitude
• Fast, with room to go even faster with upgrades installed and empty payload
• Airframe can withstand high speed
• Can be equipped with torpedoes

Cons:

• Poor defensive armament
• Very challenging to fly with only stock upgrades, with poor flight performance and disappointing payload
• Not very durable
• Carrying the 4,000 kg payload will add external pylons which will increase drag and reduce speed, flight performance, and climb rate
• Two of the SC1000L2s (externally-carried ones) drop at the same time in RB and SB
• Cramped cockpit and poor pilot protection
• Tail design creates a blind spot to the already underwhelming defensive armaments

In-game description

Dornier Do 217 M-1 medium twin-engine bomber

The creation of the next version of the Do 217 bomber was caused by a shortage of BMW 801 air-cooled engines. These engines were urgently needed for Fw 190A fighters and Ju 88G heavy night fighters.

In order to avoid interruptions in the production of Do 217K bombers, the Dornier Flugzeugwerke designers quickly redesigned the Do 217 K-1 to enable the installation of DB 603 liquid-cooled engines. The DB 603A twelve-cylinder, in-line, liquid-cooled engine had a takeoff power of 1,750 hp and was equipped with a 3.72 m diameter four-bladed propeller.

Due to the new engine's higher fuel consumption, the Do 217M's flight range was reduced by about 150 km. Nevertheless, other flight characteristics of the new variant proved to be better than those of the Do 217K; for example, the plane's maximum flight speed was increased. However, even without its combat load, the aircraft could fly with one working engine only if it was descending.

The Do 217M's armament and bomb capacity were the same as the Do 217K's, but a large-calibre 13 mm Rheinmetall-Borsig MG 131 machine gun was installed in the nose-mounted turret instead of a twin 7,92 mm Mauser MG 81Z machine gun.

Some of the production machines were equipped with FuG 216 Neptun signals intelligence systems that operated in the rear hemisphere and were used to detect radar emissions from British night fighters. The FuG 216 device's antennas were mounted on the wing surfaces.

Aircraft with DB 603A and BMW 801D engines were produced simultaneously from 1942-43. The Do 217 M-1's production was discontinued in September 1943. A total of 443 Do 217 M-1 bombers were built. In 1944, 37 machines of the M-1 variant were converted to Do 217 M-11 guided weapon carriers.

In February 1944, the British managed to get one Do 217 M-1 with minimum damage. On the night of February 23, a bomber from the KG 2 squadron had been damaged by anti-aircraft gun fire over London. The crew immediately abandoned the machine, but the aircraft flew safely about 100 more kilometres and, by itself, landed on its belly near Cambridge.
