General Electric Yj93
The General Electric YJ93 turbojet engine was designed as the powerplant for both the North American XB-70 Valkyrie bomber and the North American XF-108 Rapier interceptor. The YJ93 was a single-shaft axial-flow turbojet with a variable-stator compressor and a fully variable convergent/divergent exhaust nozzle. The maximum sea-level thrust was . Design and development The YJ93 started life as the General Electric J79-X275, an enlarged version of the General Electric J79 turbojet with "275" meaning Mach 2.75, the engine's target operating speed. This design evolved into the X279 when Mach 3 cruise became a requirement, and ultimately became the YJ93. The engine used a special high-temperature JP-6 fuel. The six YJ93 engines in the XB-70 Valkyrie were capable of producing a thrust to weight ratio of 5:1 allowing for a speed of (approximately Mach 3) at an altitude of . The first engine went on test in September 1958 and featured advanced technology achievements such as electrol ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is an affinity group for contributors with shared goals within the Wikimedia movement. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within Wikimedia project, sibling projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by ''Smithsonian Magazine, Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000".

Axial Compressor
An axial compressor is a gas compressor that can continuously pressurize gases. It is a rotating, airfoil-based compressor in which the gas or working fluid principally flows parallel to the axis of rotation, or axially. This differs from other rotating compressors such as centrifugal compressor, axi-centrifugal compressors and mixed-flow compressors where the fluid flow will include a "radial component" through the compressor. The energy level of the fluid increases as it flows through the compressor due to the action of the rotor blades which exert a torque on the fluid. The stationary blades slow the fluid, converting the circumferential component of flow into pressure. Compressors are typically driven by an electric motor or a steam or a gas turbine. Axial flow compressors produce a continuous flow of compressed gas, and have the benefits of high efficiency and large mass flow rate, particularly in relation to their size and cross-section. They do, however, require several ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

1950s Turbojet Engines
Year 195 ( CXCV) was a common year starting on Wednesday of the Julian calendar. At the time, it was known in Rome as the Year of the Consulship of Scrapula and Clemens (or, less frequently, year 948 ''Ab urbe condita''). The denomination 195 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire * Emperor Septimius Severus has the Roman Senate deify the previous emperor Commodus, in an attempt to gain favor with the family of Marcus Aurelius. * King Vologases V and other eastern princes support the claims of Pescennius Niger.

Tumansky R-15
The Tumansky R-15 is an axial-flow, single-shaft turbojet with an afterburner. Its best known use is on the Mikoyan-Gurevich MiG-25. Design and development The R-15-300 was designed at the OKB-300 design bureau led by Sergei Tumansky in the late 1950s. The engine was originally intended for the Tupolev Tu-121 high-altitude high-speed cruise missile. Due to a lack of Soviet resources and funding, the engine casing was mainly steel, and in areas exposed to high temperatures, 30-micrometre silver-plated steel. At the time, the USSR did not have the resources to exploit metals such as titanium or other alloys that could have reduced the weight of the engine. The Tu-121 was later canceled, but its basic design was used in the Tupolev Tu-123 reconnaissance drone. Performance The maximum thrust was 7,500 kilograms force (73.5 kN, 16,500 lbf) dry and 11,200 kilograms force (110 kN, 24,700 lbf) with afterburner. This thrust enabled the Mikoyan-Gurevich MiG-25, with t ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Pratt & Whitney J58
The Pratt & Whitney J58 (company designation JT11D-20) is an American jet engine that powered the Lockheed A-12, and subsequently the Lockheed YF-12, YF-12 and the Lockheed SR-71 Blackbird, SR-71 aircraft. It was an afterburning turbojet engine with a unique compressor bleed to the afterburner that gave increased thrust at high speeds. Because of the wide speed range of the aircraft, the engine needed two modes of operation to take it from stationary on the ground to at altitude. It was a conventional afterburning turbojet for take-off and acceleration to Mach 2 and then used bleed air, permanent compressor bleed to the afterburner above Mach 2. The way the engine worked at cruise led it to be described as "acting like a turboramjet". It has also been described as a turboramjet based on incorrect statements describing the turbomachinery as being completely bypassed. The engine performance that met the mission requirements for the CIA and USAF over many years was later enhanced ...

Orenda Iroquois
The Orenda PS.13 Iroquois was an advanced turbojet engine designed for military use. It was developed by the Canadian aircraft engine manufacturer Orenda Engines, a part of the Avro Canada group. Intended for the CF-105 Arrow interceptor, development was cancelled, along with the Arrow, in 1959. Design history For the CF-105 Arrow project, Avro Canada had originally intended to use one of three different engines, all UK designs: Rolls-Royce RB.106, the Bristol B.0L.4 ''Olympus'', or a license-built version of the Olympus, the Curtiss-Wright J67. The RB.106 and J67 were selected as the primary and backup engines for the new design. However, both the RB.106 and J67 were cancelled during the Arrow's design phase, too far into the program to select the Olympus. Orenda Engines quickly responded with the PS.13 Iroquois design. In overall design terms, the PS.13 was similar to the RB.106, using a "two-spool" layout with low-pressure and high-pressure sections of the compresso ...

Kolesov RD-36-51
The Kolesov RD-36 was a supersonic turbojet engine used on various Soviet aircraft projects. Design and development Developed at OKB-36 (P. A. Kolesov) and produced at the Rybinsk Motor-Building Plant, the RD-36-51A engine was developed for the Tu-144D supersonic passenger aircraft. A simplified version with a fixed nozzle for the high-altitude Myasishchev M-17 was designated RD-36-51B. The engine developed a thrust of . The RD36-51A engine passed all state bench and flight tests in 1973–75 (with flight testing on the Tu-144D). The engine's specifications were: * Maximum thrust at take-off = * Maximum thrust during supersonic cruise = altitude = , speed = * Maximum thrust during subsonic cruise= altitude = , speed = * Temperature = * Diameter = * Length = * Weight = For the high-altitude M-17 "Stratosphera" aircraft (NATO reporting name Mystic-A) a single-shaft TRD RD36-51B was created.
