Following the conversions of the two Su-27M prototypes, ... Maximum speed: Mach 2.25 1,400 km/h (870 mph; 760 kn), Mach 1.13 at sea level;
At Mach 0.65, u is 65% of the speed of sound (subsonic), and, at Mach 1.35, u is 35% faster than the speed of sound (supersonic). An F/A-18 Hornet creating a vapor cone at transonic speed just before reaching the speed of sound. The local speed of sound, and hence the Mach number, depends on the temperature of the surrounding gas.
An unusual addition to the R-25 was an emergency mode thrust boost which increased the compressor speed to 106% and also increased the afterburner fuel flow with the addition of a second afterburner fuel pump. Thrust was increased to 96.5 kilonewtons (21,700 lb f) below an altitude of 2,000 metres (6,600 ft). The time limit for its use was 1 ...
The conversions (Project 675M) could be distinguished by the fitting bulges either side of the sail. Three of these modified units were further upgraded under Project 675MKV towards the end of the Cold War. The P-1000 Vulkan (GRAU 3M70) flew faster (Mach 2.3–2.5) [4] than the P-500 and its range was extended to 700 kilometres (430 mi). [4]
The Global 8000 was initially a shorter, three-zone aircraft but was updated in May 2022 as a four-zone jet similar to the Global 7500, reaching 8,000 nmi (14,800 km) and with a top speed of Mach 0.94, making it the fastest business jet and fastest civilian aircraft since Concorde. The Global 8000 is scheduled to be introduced in 2025.
The Mikoyan MiG-29 (Russian: Микоян МиГ-29; NATO reporting name: Fulcrum) is a twin-engine fighter aircraft designed in the Soviet Union.Developed by the Mikoyan design bureau as an air superiority fighter during the 1970s, the MiG-29, along with the larger Sukhoi Su-27, was developed to counter U.S. fighters such as the McDonnell Douglas F-15 Eagle and the General Dynamics F-16 ...
Speed is the magnitude of velocity (a vector), which indicates additionally the direction of motion. Speed has the dimensions of distance divided by time. The SI unit of speed is the metre per second (m/s), but the most common unit of speed in everyday usage is the kilometre per hour (km/h) or, in the US and the UK, miles per hour (mph).
The Yasen class, Russian designations Project 885 Yasen and Project 885M Yasen-M (Russian: Ясень, lit. 'ash tree', NATO reporting name: Severodvinsk), also referred to as the Graney class, are a series of nuclear-powered cruise missile submarines designed by the Malakhit Marine Engineering Bureau and built by Sevmash for the Russian Navy.
