Progress D-27
The Progress D-27 is a three-shaft propfan engine developed by Ivchenko Progress. The gas generator was designed using experience from the Lotarev D-36 turbofan. The D-27 engine was designed to power more-efficient passenger aircraft such as the abandoned Yakovlev Yak-46 project, and it was chosen for the Antonov An-70 military transport aircraft. As of 2019, the D-27 is the only contra-rotating propfan engine to enter service. Design and development The engine was launched in 1985 by the Ivchenko-Progress Design Bureau for commercial and military transport aircraft. It was designed to meet the expected growth in demand for new aero engines for civil and military applications. It has a take-off rating of for the Antonov An-70. Gunston lists ratings between for the engine. In 1990, the D-27 engine was proposed for the 150-162 seat Yakovlev Yak-46 airliner. This twin-engined derivative of the three-engine Yakovlev Yak-42 would mount the two D-27 engines on the rear fuselage. A ...

Antonov An-70
The Antonov An-70 ( uk, link=no, Антонов Ан-70) is a four-engine medium-range transport aircraft Transport aircraft is a broad category of aircraft that includes: * Airliners, aircraft, usually large and most often operated by airlines, intended for carrying multiple passengers or cargo in commercial service * Cargo aircraft or freighters, fix ..., and the first aircraft to take flight powered only by propfan engines. It was developed in the late 1980s by the Antonov Design Bureau to replace the obsolete Antonov An-12, An-12 military transport aircraft. The maiden flight of the first prototype took place in December 1994 in Kyiv, now independent Ukraine. Within months the prototype had suffered a mid-air collision. A second airframe was produced to allow the flight-test programme to proceed. Both prototypes were produced by the Antonov Serial Production Plant, Kyiv Aircraft Production Plant. Following the dissolution of the Soviet Union in the early 1990s, the program ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flight Testing
Flight testing is a branch of aeronautical engineering that develops specialist equipment required for testing aircraft behaviour and systems. Instrumentation systems are developed using proprietary transducers and data acquisition systems. Data is sampled during the flight of an aircraft, or atmospheric testing of launch vehicles and reusable spacecraft. This data is validated for accuracy and analyzed before being passed to specialist engineering groups for further analysis to validate the design of the vehicle. The flight test phase accomplishes two major tasks: 1) finding and fixing any design problems and then 2) verifying and documenting the vehicle capabilities for government certification or customer acceptance. The flight test phase can range from the test of a single new system for an existing vehicle to the complete development and certification of a new aircraft, launch vehicle, or reusable spacecraft. Therefore, the duration of a particular flight test program c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tupolev Tu-334
The Tupolev Tu-334 (russian: Туполев Ту-334) was a Russian short-to-medium range airliner project that was developed to replace the ageing Tu-134s and Yak-42s in service around the world. The airframe was based on a shortened Tupolev Tu-204, Tu-204 fuselage and a scaled-down version of that aircraft's wing. Unlike the Tu-204, however, the Tu-334 has a T-tail and engines mounted on the sides of the rear fuselage instead of under the wings. With the nationalisation of the Russian aircraft companies in 2009 to form United Aircraft Corporation it was decided not to continue with the programme. Development The Tupolev Design Bureau introduced the Tu-334 in early 1989 as an eventual propfan-powered airliner to potentially enter service for Aeroflot in 1995. However, it would have an interim turbofan-powered version that would begin airline service around 1991–1992. Consuming about 20 percent less fuel than the best Soviet turbofan, the propfan engine would be a then-u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mil Mi-26
The Mil Mi-26 (russian: link=no, Миль Ми-26, NATO reporting name: Halo) is a Soviet/Russian heavy transport helicopter. Its product code is ''Izdeliye 90''. Operated by both military and civilian operators, it is the largest and most powerful helicopter to have gone into serial production. Design and development Following the incomplete development of the heavier Mil Mi-12 (prototypes known as Mil V-12) in the early 1970s, work began on a new heavy-lift helicopter, designated as the ''Izdeliye 90'' ("Project 90") and later allocated designation ''Mi-26''. The new design was required to have an empty weight less than half its maximum takeoff weight. The helicopter was designed by Marat Tishchenko, protégé of Mikhail Mil, founder of the OKB-329 design bureau. The Mi-26 was designed to replace earlier Mi-6 and Mi-12 heavy lift helicopters and act as a heavy-lift helicopter for military and civil use, having twice the cabin space and payload of the Mi-6, then the world ...

Turboshaft
A turboshaft engine is a form of gas turbine that is optimized to produce shaftpower rather than jet thrust. In concept, turboshaft engines are very similar to turbojets, with additional turbine expansion to extract heat energy from the exhaust and convert it into output shaft power. They are even more similar to turboprops, with only minor differences, and a single engine is often sold in both forms. Turboshaft engines are commonly used in applications that require a sustained high power output, high reliability, small size, and light weight. These include helicopters, auxiliary power units, boats and ships, tanks, hovercraft, and stationary equipment. Overview A turboshaft engine may be made up of two major parts assemblies: the 'gas generator' and the 'power section'. The gas generator consists of the compressor, combustion chambers with ignitors and fuel nozzles, and one or more stages of turbine. The power section consists of additional stages of turbines, a gear reduction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aircraft Noise Pollution
Aircraft noise pollution refers to noise produced by aircraft in flight that has been associated with several negative stress-mediated health effects, from sleep disorders to cardiovascular ones. Governments have enacted extensive controls that apply to aircraft designers, manufacturers, and operators, resulting in improved procedures and cuts in pollution. Sound production is divided into three categories: * Mechanical noise—rotation of the engine parts, most noticeable when fan blades reach supersonic speeds. * Aerodynamic noise—from the airflow around the surfaces of the aircraft, especially when flying low at high speeds. * Noise from aircraft systems—cockpit and cabin pressurization and conditioning systems, and Auxiliary Power units. Mechanisms of sound production Aircraft noise is noise pollution produced by an aircraft or its components, whether on the ground while parked such as auxiliary power units, while taxiing, on run-up from propeller and jet exhaust, duri ...

1995 Borodianka Mid-air Collision
On 10 February 1995 at 16:09 CET, the first Antonov An-70 prototype aircraft collided with an Antonov An-72 that was assisting with the An-70 test program over Borodianka Raion in Ukraine. All seven crew members on board the An-70 were killed; the An-72 was able to make a safe emergency landing at Gostomel Airport in Kyiv with no fatalities. Causes A Ukrainian-led commission reported that the cause was human error and blamed the flight maneuvers by the crew as the major contributing factor to the crash. Leonid Berestov is quoted as saying "The careless actions of both crews in their formation flying led to a collision and crash. Several faults were observed in the three test flights that took place before the accident flight, including flight control problems during the second flight and again during the third flight, on the day preceding the crash.
