The Molniya (now Vympel) R-60 (NATO reporting name: AA-8 "Aphid") is a short-range lightweight infrared homing air-to-air missile designed for use by Soviet fighter aircraft. It has been widely exported , and remains in service with the CIS and many other nations.
A depth gauge is an instrument for measuring depth below a vertical reference surface. They include depth gauges for underwater diving and similar applications. A diving depth gauge is a pressure gauge that displays the equivalent depth below the free surface in water. The relationship between depth and pressure is linear and accurate enough ...
The intention of the suit is to keep the escapee dry and protected from cold shock during ascent, and to provide buoyancy, freeboard, and thermal insulation at the surface. [ 2 ] [ 3 ] Following a nearly 30-year hiatus, the U.S. Navy reinstituted pressurized submarine escape training (PSET) for submarine sailors in 2009, using the Beaufort Mk ...

An insulation monitoring device monitors the ungrounded system between an active phase conductor and earth. It is intended to give an alert (light and sound) or disconnect the power supply when the resistance between the two conductors drops below a set value, usually 50 k Ω (sample of IEC standard for medical applications).
Spray foam insulation or spray polyurethane foam (SPF) is an alternative to traditional building insulation such as fiberglass. A two-component mixture composed of isocyanate and polyol resin comes together at the tip of a gun, and forms an expanding foam that is sprayed onto roof tiles, concrete slabs, into wall cavities, or through holes ...
The depth of penetration from the zero datum is measured, on which a harder material gives a lower measure. That is, the penetration depth and hardness are inversely proportional. The Rockwell test does not use any optical equipment to measure the hardness indention, rather all calculations are done within the machine to measure the indention ...
RGB-60 (Rocket Guided Bomb model 60) is a Russian anti-submarine weapon with a range of 5,700–6,000 m that can function to depths of 500 m. They can be fired from ships in salvos of up to 12 using the RBU-6000. [1] India has several local versions of the RGB-60. An indigenous version by HAPP and Tiruchi was reported in 2010. [2]
