The 9×18mm Makarov (designated 9mm Makarov by the C.I.P. and often called 9×18mm PM) is a pistol and submachine gun cartridge developed in the former USSR. During the latter half of the 20th century, it was a standard military pistol cartridge of the Soviet Union and the Eastern Bloc, analogous to the 9×19mm Parabellum in NATO and Western Bloc military use.
In the 1972–1973 time frame, Walther introduced the Walther PP Super, chambered in 9×18mm Ultra for the West German Police. It might have been influenced by the success of the Soviet 9×18mm Makarov, although most observed the opposite (the Ultra cartridge is usually agreed to have been the design basis for the Makarov, with similar case length and a slightly wider and shorter projectile).
The X-48B has a 21-foot (6.4 m) wingspan, weighs 392 pounds (178 kg), and is built from composite materials. It is powered by three small turbojet engines and is expected to fly at up to 120 kn (220 km/h) and reach an altitude of 10,000 feet (3,000 m). [11] [12] The X-48B is an 8.5% scaled version of a conceptual 240 feet (73 m) span design.
An ultraluminous X-ray source ( ULX) is an astronomical source of X-rays that is less luminous than an active galactic nucleus but is more consistently luminous than any known stellar process (over 10 39 erg /s, or 10 32 watts ), assuming that it radiates isotropically (the same in all directions). Typically there is about one ULX per galaxy in ...
List of X-planes. The X-planes are a series of experimental United States aircraft and rockets, used to test and evaluate new technologies and aerodynamic concepts. They have an X designator within the US system of aircraft designations, which denotes the experimental research mission. Not all US experimental aircraft have been designated as X ...
The X-44 was designed by Lockheed Martin to demonstrate the feasibility of an aircraft controlled by vectored thrust alone. The X-44 design had a reduced radar signature (due to lack of tail and vertical stabilizers) and was made more efficient by eliminating the tail and rudder surfaces, and instead using thrust vectors to provide yaw, pitch ...
Ultra-high-energy cosmic ray. In astroparticle physics, an ultra-high-energy cosmic ray ( UHECR) is a cosmic ray with an energy greater than 1 EeV (10 18 electronvolts, approximately 0.16 joules ), [1] far beyond both the rest mass and energies typical of other cosmic ray particles. These particles are extremely rare; between 2004 and 2007, the ...
See Figure 1. To simplify, let the magnetic field point in the z-direction and vary with location x, and let the conductor translate in the positive x-direction with velocity v. Consequently, in the magnet frame where the conductor is moving, the Lorentz force points in the negative y-direction, perpendicular to both the velocity, and the B-field.
