definition of hypervelocity for missiles
a8ab0c48fc497f34840f71969ed2bbf1
Hypervelocity Hypervelocity refers to velocities in the range from a few kilometers per second to some tens of kilometers per second. This is especially relevant in the field of space exploration and military use of space, where hypervelocity impacts can result in anything from minor component degradation to the complete destruction of a spacecraft or missile.

critical angle Also called angle of stall, critical angle of attack, stalling angle. Aeronautics. the angle of attack, greater than or equal to the angle of attack for maximum lift, at which there is a sudden change in the airflow around an airfoil with a subsequent decrease in lift and increase in drag.

Strategic Arms Limitations Talks/Treaty (SALT) I and II For the first time during the Cold War, the United States and Soviet Union had agreed to limit the number of nuclear missiles in their arsenals. SALT I is considered the crowning achievement of the Nixon-Kissinger strategy of detente. détenteohnson therefore called for strategic arms limitations talks (SALT), and in 1967, he and Soviet Premier Alexei Kosygin met at Glassboro State College in New Jersey.

Aircraft For long range jet operating in the stratosphere, the speed of sound is constant, hence flying at fixed angle of attack and constant Mach number causes the aircraft to climb, without changing the value of the local speed of sound. In this case: where is the cruise Mach number and the speed of sound.erry range means the maximum range the aircraft can fly. This usually means maximum fuel load, optionally with extra fuel tanks and minimum equipment. It refers to transport of aircraft for use on remote location without any passengers or cargo.

The 10 longest range Intercontinental Ballistic Missiles (ICBM) The Bulava or RSM-56 (NATO code name: SS-NX-32) is a new intercontinental-range, submarine-launched ballistic missile of the Russian Navy. The missile, with a range of about 10,000km, is intended for Borey-class nuclear submarines.

Supersonic speed Supersonic travel is a rate of travel of an object that exceeds the speed of sound. For objects traveling in dry air of a temperature of 20 °C at sea level, this speed is approximately 343 m/s, 1,125 ft/s, 768 mph, 667 knots, or 1,235 km/h. Speeds greater than five times the speed of sound are often referred to as hypersonic. Flights during which only some parts of the air surrounding an object, such as the ends of rotor blades, reach supersonic speeds are called transonic. This occurs ...

0 100%FREQUENCYRegularly used63 /100 Hypersonic speed. In aerodynamics, a hypersonic speed is one that is highly supersonic. Since the 1970s, the term has generally been assumed to refer to speeds of Mach 5 and above. The precise Mach number at which a craft can be said to be flying at hypersonic speed varies, since individual physical changes in the airflow occur at different speeds; these effects collectively become important around Mach 5. The hypersonic regime is often alternatively defined as speeds where ramjets do not produce net thrust.

Chinese Hypersonic Engine Wins Award, Reshapes Speed Race? Such a combined engine would use subsonic speeds to takeoff, power the ramjet to high supersonic speeds, before transforming into scramjet mode for speeds above Mach 5. Lockheed Martin has proposed using a similar concept of combined engines for the Mach 6 SR-72, a near-space UAV, to the US Air Force.

Ballistic missile This contrasts to a cruise missile, which is aerodynamically guided in powered flight. Long range intercontinental ballistic missiles (ICBM) are launched at a steep, sub-orbital flight trajectory and spend most of their flight out of the atmosphere. Shorter range ballistic missiles stay within the Earth's atmosphere.

How does a Ballistic Missile Work? A ballistic missile is a type of large and powerful missile designed to deliver a warhead across large distances to a predetermined target.

Scramjet Then from 1992 to 1998 an additional 6 flight tests of the axisymmetric high-speed scramjet-demonstrator were conducted by CIAM together with France and then with NASA, USA. Maximum flight velocity greater than Mach 6.4 was achieved and Scramjet operation during 77 seconds was demonstrated.

Hyperviscosity syndrome Hyperviscosity syndrome. Hyperviscosity syndrome is a group of symptoms triggered by increase in the viscosity of the blood. Symptoms of high blood viscosity include spontaneous bleeding from mucous membranes, visual disturbances due to retinopathy, and neurologic symptoms ranging from headache and vertigo to seizures and coma. Hyperviscosity occurs from pathologic changes of either cellular or protein fractions of the blood such as is found in polycythemias, multiple myeloma, leukemia, monoclonal gammopathies such as W

- I might just want to add about how, while the terms hypersonic and supersonic refer to the speed of a type of missile as measured in Mach number. A supersonic and hypersonic missile travels several times faster than the speed of sound (measured in Mach). While a subsonic missile travels slower than Mach 1 .

Ballistic missile When in space and no more thrust is provided, the missile enters free-flight. In order to cover large distances, ballistic missiles are usually launched into a high sub-orbital spaceflight; for intercontinental missiles, the highest altitude (apogee) reached during free-flight is about 1200 km.

WHAT IS HYPERKYPHOSIS? Hyperkyphosis is the term given to an accentuated thoracic spinal curvature.Hyperkyphosis in children is usually due to the disease known as “Scheuermann’s Kyphosis” or it can be postural (wedging of 3 or more vertebral bodies and discs). In children, a thoracic curve greater than 50° is termed as “hyperkyphosis”.yperkyphosis in adults can have many contributory factors, the most notable being vertebral fractures and/or osteoporosis as well as posture. In adults, a thoracic curve above 60° is generally classed as “Hyperkyphosis”.

- The advanced Topol missile has three cruise engines and can develop hypersonic speed. The high thrust-to-weight ratio allows the warhead to manoeuvre on the trajectory and pass through a dense air defence system.. At that time, not many defence analysts thought much of the report.

Strategic Arms Limitation Talks The Strategic Arms Limitation Talks (SALT) were two rounds of bilateral conferences and corresponding international treaties involving the United States and the Soviet Union —the Cold War superpowers —on the issue of armament control. The two rounds of talks and agreements were SALT 1 and SALT 2.Negotiations commenced in Helsinki, Finland, in November 1969. SALT I led to the Anti-Ballistic Missile Treaty and an interim agreement between the two countries.Although SALT II resulted in an agreement in 1979, the United States chose not to ratify the treaty in response to the Soviet war in Afghanistan, which took place later that year.The agreement expired on December 31, 1985 and was not renewed.ALT I led to the Anti-Ballistic Missile Treaty and an interim agreement between the two countries.

- Bombogenesis is cyclogenesis taken to the extreme. Bombogenesis is defined as a mid-latitude cyclone that drops in surface barometric pressure by 24 or more millibars in a 24-hour period. The height contours pack around the center of rotation and the number of height contours increases rapidly in the developing stages.

- Aerodynamics, from Greek ἀήρ aer (air) + δυναμική (dynamics), is a branch of Fluid dynamics concerned with studying the motion of air, particularly when it interacts with a solid object, such as an airplane wing.n aerodynamics, hypersonic speeds are speeds that are highly supersonic. In the 1970s, the term generally came to refer to speeds of Mach 5 (5 times the speed of sound) and above. The hypersonic regime is a subset of the supersonic regime.
