Miscellaneous Subjects / Rohr 2-175

« on: October 14, 2021, 11:28:21 AM »

Burt Raynes, president of the aerospace company Rohr Industries, decided to enter the light aviation market in 1974. The famous designer Walter E. Mooney was invited to develop the first aircraft. The project received the designation 71X, but was later renamed 2-175. October 14, 1974 - the first flight of the Rohr 2-175 light aircraft.

Mooney designed a low-wing aircraft with a triangular wing and a non-retractable landing gear. The aircraft was made of fiberglass-reinforced plastic. The Lycoming engine (150 hp) rotated the pusher screw in the annular fairing. The name 2-175 meant that the plane had 2 seats for the pilot and passenger and its speed was 175 mph (281.63 km/h)

Rohr 2-175 performed well during test flights. But Roper Industries started having financial problems and the project had to be curtailed. We managed to build only 2 flying prototypes and 1 aircraft for ground testing. They (as well as all project documentation) were disposed of.

Miscellaneous Subjects / Junkers Ju 52/1m

« on: October 13, 2021, 04:37:02 PM »

Junkers Luftverkehr Persian airline, which was part of Junkers Flugzeug- und Motorenwerke, in 1929 proposed to develop a new transport aircraft. The main requirements are the transportation of 2 tons of cargo at a distance of 800 km. The work on the Ju 52/1m project was started by a team of engineers led by Ernst Zindel. October 13, 1930 - the first flight of the Junkers Ju 52/1m transport aircraft.

It was an all-metal low-wing with a non-retractable landing gear (wheeled, ski and float) and a typical Junkers corrugated duralumin skin. It was equipped with a BMW VII engine (504 hp) Cruising speed - 165 km / h, flight range - 1500 km. Took on board 15 passengers or 2170 kg of cargo.

The Ju 52/1m was not particularly successful ? only 7 aircraft were built. The reason is banal ? one engine was not enough both in power and in terms of safety. Therefore, Zindel converted the Ju 52/1m into a three-engine aircraft. This is how the famous and much more successful Ju 52/3m appeared.

"In Grim"

The first reaction to these photos may be "Wow! A Soviet plane in an Italian airline." But, alas, Tu-104A jet airliners have never flown under the Alitalia flag. But then why is this plane so painted? The answer is simple - for filming.

In 1975, a joint Soviet-Czechoslovak film "Cirkus v cirkuse" ("Solo for an elephant with an orchestra") was shot in Czechoslovakia. According to the scenario, an Italian airline plane was needed. The film crew tried to rent a real airliner, but the Italians asked too high a price. Therefore, his role was "played" by the decommissioned Tu-104A a/k Českoslavensk? aerolinie (ČSA) with the used OK-NDF. He "became" a Douglas DC-8-62 with a used I-DIWN. It is noteworthy that only one side was painted.

P.S. You can watch the movie here: episode 1 (https://youtu.be/mZL3eexUziI), series 2 (https://youtu.be/Fl5yN6EpJpc ). At the beginning of the first series, you can see Domodedovo Airport of those years with Aeroflot, KLM, Air France airliners, etc.

P.P.S. And that's how the Yak-9 "played the role" of the British Supermarine Spitfire Mk.V fighter

Combat Warplanes / FMA Ae. MB.2

« on: October 09, 2021, 03:54:16 PM »

In 1932, the Argentine Army commissioned the Institute of Aeronautics in Cordoba to develop a light bomber. It was intended to replace the outdated French-made Breguet XIX. Fabrica Militar de Aviones (FMA) was to produce the new aircraft. It received the designation FMA Ae. MB.2 Bambi. October 9, 1935 - the first flight of the FMA Ae. MB.2 Bombi light bomber.

It was a low-wing of a mixed design (wooden wing + fuselage made of duralumin pipes + linen skin) with a non-retractable landing gear. It was equipped with a Wright SGR-1820-F3 Cyclone engine (715 hp) Maximum speed - 285 km/ h, flight range - 600 km. Armament ? 7.65 mm machine gun + 11.43 mm machine gun + up to 400 kg of bombs. The first variants were equipped with a turret of 2 ? 7.65 mm machine guns.

Tests have shown that Ae. MB.2 Bombi is inferior to foreign analogues. But it was still put into mass production. 15 bombers were released, which carried out reconnaissance and patrol missions in the Argentine Air Force.

Miscellaneous Subjects / Aero 45

« on: October 08, 2021, 12:45:32 PM »

The Aero 45S "Super Aero" light aircraft stands in front of transport containers, in which its brethren are already packed in disassembled form. Czechoslovakia, 1959. It can be seen that the screws and wing consoles were removed from the aircraft for transportation, and the cockpit glazing was also closed. The inscription "Aeroflot" and used CCCP-92906 clearly indicate to us the recipient of the cargo - the USSR. According to the flight number, it was possible to find out that the planes in the photo went to the Kazakh SSR.

"Super Aero" differed from its predecessor with more advanced navigation equipment. The definition of "air taxi" was ideally suited to the entire Aero 45 line. These planes could fly at different times of the day and in difficult weather conditions. "45" indicates a capacity of 4-5 passengers in a spacious cabin. In addition to friends under the Warsaw Pact, Aero 45 were also delivered to Western countries - Italy and Switzerland.

Miscellaneous Subjects / Langley Aerodrome A

« on: October 07, 2021, 09:09:39 PM »

Attempts at manned flight on an aircraft with an engine were made even before the flight of the Wright brothers' Flyer I. One of the closest to success was the inventor Samuel Langley, secretary of the Smithsonian Institution. After successful flights of unguided models with a steam engine, in 1898 he received a grant from the US Army to develop a manned airplane. October 7 , 1903 - the first attempt to fly an airplane Langley Aerodrome A.

By 1903, Aerodrome A was built with tandem wings, a cruciform tail and a 52 hp Manly engine. A barge with a catapult was supposed to be used for takeoff.

Aerodrome was tested over the Potomac River under the control of engineer Charles Manly. Unfortunately, he crashed into the water immediately after takeoff. Manly was not injured and the plane was decided to be restored. The second attempt took place on December 8, 1903 and was also unsuccessful. And after 9 days, the Wright brothers flew.

"Intruder"

On July 1, 1968, the Douglas DC-8 Super 63CF airliner of Seaboard World Airlines with b/n N8631 took off from the McCord military Base, USA, and headed for Japan, to Yokota Air Base. There were 24 crew members and 214 military personnel on board, who were flying from vacations and hospitals to South Vietnam. During the flight, the airliner deviated from the course by ~ 150 km and flew over the Kuril Islands, thereby violating the state border of the USSR.

A MiG-17 link was raised to intercept, forcing the violator to land at the Burevestnik (Буревестник) airfield on Iturup Island. Warning shots were fired for this purpose. During and after the interception of the DC-8, its crew and passengers were not injured. Although the first landing approach could have ended in disaster ? the American airliner miraculously did not crash into the Grozny volcano. But KVS Joseph D. Tosolini successfully landed his plane on a runway a little more than 1200 meters long. The crew, passengers and the DC-8 itself were on the island of Iturup for two days, after which they were released.

Combat Warplanes / Hawker Tornado

« on: October 06, 2021, 05:06:23 PM »

The Hawker Hurricane fighter has just been put into service, and Hawker Siddeley Aircraft has already begun work on its replacement. In parallel, 2 projects developed - N-type (Napier Sabre engine) and R-type (Rolls-Royce Vulture engine). The R-type fighter was designated Tornado. In the spring of 1938, the British Aviation Ministry ordered the construction of a prototype. October 6, 1939 - the first flight of the Hawker Tornado piston fighter.

The Tornado was a single-seat low-wing with a retractable landing gear. The first prototype was powered by a Rolls-Royce Vulture II engine (1,760 hp) with a maximum speed of 641 km/h and a flight range of 965 km. Armament ? 12 ? 7.7mm Browning machine guns or 4 ? 20 mm Hispano guns.

Although the preliminary tests ended successfully, but due to problems with the Tornado engine, it was never put into mass production. Only 4 prototypes were built, on which different engines were tested, and later propellers. The project was closed in 1942.

Miscellaneous Subjects / SNCASE SE-2100

« on: October 04, 2021, 05:20:17 PM »

In 1944, the Soci?t? nationale des constructions aeronautiques du Sud-Est (SNCASE) began work on the project of a light two-seat aircraft SE.2100. The project was led by designer Pierre Satre? the future chief designer of the supersonic airliner A?rospatiale/BAC Concorde. October 4, 1945 - the first flight of the light aircraft SNCASE SE-2100 (aka Sud-Est SE-2100).

The SE.2100 was an all-metal low-wing tailless plane with a swept (55?) wing and a non-retractable landing gear. The Renault 4Pei engine (190 hp) rotated the pusher screw. Cruising speed ? 198 km / h. Flight range - 500 km.

In fact, the SE.2100 was an experimental aircraft for testing the "tailless" scheme. It was built in a single copy and was not planned to be put into mass production. After its first flight under the control of pilot Pierre Cadot, the SE.2100 was tested for several more years. After 1952, his traces are lost.
