Myasishchev M-55

Myasishchev M-55 is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Myasishchev M-55 rather than just read about it. In short: The Myasishchev M-55 (NATO reporting name: Mystic-B) is a high-altitude reconnaissance aircraft developed by OKB Myasishchev in the Soviet Union, similar in mission to the Lockheed U-2, but with a twin-boom fuselage and tail surface design. It is a twin-engined development of the Myasishchev M-17 Stratosphera with a higher maximum take-off weight.

Reference excerpt

The Myasishchev M-55 (NATO reporting name: Mystic-B) is a high-altitude reconnaissance aircraft developed by OKB Myasishchev in the Soviet Union, similar in mission to the Lockheed U-2, but with a twin-boom fuselage and tail surface design. It is a twin-engined development of the Myasishchev M-17 Stratosphera with a higher maximum take-off weight.

Design and development

During the 1950s and 1960s the United States instituted several programs using high-altitude reconnaissance balloons, released over friendly territory to ascend into the jetstream and be transported over the Soviet Union and People's Republic of China.

Subject 34 To combat these high-altitude balloons, Myasishchev proposed Subject 34 a single-seat turbojet-powered twin-boom high-aspect-ratio aircraft. Armament of the single-seat balloon interceptor was to have been two air-air missiles (AAM) and two GSh-23 cannon with 600 rounds per gun in a dorsal turret. Before Subject 34 could be developed into operational hardware, the threat receded due to the success of the Keyhole reconnaissance satellites of the Corona program and the emergence of the Lockheed A-12. The first prototype of Subject 34 was completed in secret at the Kumertau helicopter plant in Bashkirya, but whilst carrying out taxi tests in December 1978, the prototype Chaika piloted by K. V. Chernobrovkin lifted off to avoid hitting snow banks and was destroyed after hitting a hillside in zero visibility.

M-17 Stratosphera

The design of the Chaika was adapted as a reconnaissance aircraft and emerged as the Myasishchev M-17 Stratosphera with a revised airframe, including straight tapered wings with 2° 30' anhedral (0° at 1g), shorter fuselage pod and unreheated (non-afterburning) Kolesov RD-36-51 turbojet engine. Flown for the first time on 26 May 1982, the M-17 prototype (regn CCCP 17401) was soon allocated the NATO reporting name Mystic-A and was used for investigating the ozone layer over Antarctica in 1992. The M-17 also set a total of 12 FAI world records, 5 of which still stand. On 28 March 1990, M-17 CCCP 17401 piloted by Vladimir V. Arkhipenko set an altitude record of 21,830 m (71,620 ft) in class C-1i (Landplanes: take-off weight 16 000 to 20 000 kg).

M-55 Geophysica The M-17 balloon-interceptor-based model was terminated in 1987 and replaced by the M-17RN, later known as the M-55 Geophysica, NATO reporting name Mystic-B. First flown on 16 Aug 1988, the M-55 airframe was revised further with a longer fuselage pod, housing two Soloviev D-30-10V un-reheated turbofan engines, shorter-span wings and comprehensive sensor payload. The M-55 set a total of 15 FAI world records, all of which still stand today: On 21 September 1993, an M-55 piloted by Victor Vasenkov from the 8th State R&D Institute of the Air Force named after V. P. Chkalov at Akhtubinsk reached a class record altitude of 21,360 m (70,080 ft) in class C-1j (Landplanes: take-off weight 20,000 to 25,000 kg (44,000 to 55,000 lb)). A dual-control version, the M-55UTS, was developed by adding a second cockpit behind the original, displacing some avionics and/or sensor payload. A number of M-55 Geophysica remained in service into the 1990s, performing in research roles; one M-55 took part in a study of the Arctic stratosphere in 1996–1997, with similar experiments performed in Antarctica during 1999. An Irish-headquartered company Qucomhaps, with a focus on Southeast Asia, has entered a 1-billion USD deal to use the M-55 as a high-altitude platform station for digital communications.

Service history As of 2023, the UK Ministry of Defence believes that Russia is working to return the one flyable M-55 aircraft to military service for use in the Russian invasion of Ukraine.

Variants Subject 34 The prototype of a high-altitude balloon interceptor, dubbed Chaika (Gull), was completed in secret at the Kumertau helicopter plant in Bashkirya. M-17 Stratosphera A reconnaissance version of Subject 34, given the NATO reporting name Mystic-A, powered by a single Kolesov RD-36-51 turbojet engine. At least two M-17 aircraft were built. M-17RN Initial designation of what was to become the M-55. M-55 Geophysica A refined version of the M-17 powered by two Soloviev D-30-10V unreheated turbofans, carrying a wide variety of sensors for Earth-sciences research. Five M-55 aircraft were built, including one M-55UTS. M-55Sh Proposed ground attack variant. Not built. M-55UTS A dual-control trainer version of the M-55 with a second cockpit directly aft of the forward cockpit, displacing some of the avionic/sensor payload, otherwise identical to the M-55. Geophysica 2 a more advanced Earth-sciences research aircraft derived from the M-55, which was not built.

Accidents and incidents December 1978 - Prototype Myasishchev M-17-1 Chayka high-altitude interceptor, painted in Aeroflot colours and bearing civil registration CCCP-17100, becomes accidentally airborne during initial taxi trial at Kumertau, when, in poor visibility, the starboard aileron accidentally lowered and aircraft turned abruptly. Pilot, Kir Chernobrovkin, takes off to avoid snow heap, but wingtip subsequently hits hillside and the prototype was destroyed, pilot KWF.

Worked examples

Example 1 — a first encounter with Myasishchev M-55

Start with the simplest possible case. Write down what Myasishchev M-55 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Myasishchev M-55 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Myasishchev M-55 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Myasishchev M-55

In research: Myasishchev M-55 appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Myasishchev M-55 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Myasishchev M-55 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1980s Soviet military reconnaissance aircraft, Aircraft first flown in 1988, Aircraft with retractable tricycle landing gear, so understanding it makes those chapters shorter.
In everyday life: Look for Myasishchev M-55 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
