V speeds. A single-engined Cessna 150L's airspeed indicator indicating its V-speeds in knots. In aviation, V-speeds are standard terms used to define airspeeds important or useful to the operation of all aircraft. [1] These speeds are derived from data obtained by aircraft designers and manufacturers during flight testing for aircraft type ...
The V-1 flying bomb (German: Vergeltungswaffe 1 "Vengeance Weapon 1" [a]) was an early cruise missile. Its official Reich Aviation Ministry (RLM) designation was Fieseler Fi 103[3] and its suggestive name was Höllenhund (hellhound). It was also known to the Allies as the buzz bomb or doodlebug[4][b] and in Germany as Kirschkern (cherry stone ...
V-1 flying bomb V-2 missile V-3 cannon. V-weapons, known in original German as Vergeltungswaffen (German pronunciation: [fɐˈgɛltʊŋsˌvafṇ], German: "retaliatory weapons", "reprisal weapons"), were a particular set of long-range artillery weapons designed for strategic bombing during World War II, particularly strategic bombing and/or aerial bombing of cities.
Intelligence reports on the V-1 and V-2. After V-2 flight testing began at the Blizna V-2 missile launch site (the first launch from there was on November 5, 1943), the AK had a unique opportunity to gather more information and to intercept parts of test rockets (most of which did not explode). The AK quickly located the new testing ground at ...
V-2 rocket. The V2 (German: Vergeltungswaffe 2, lit. 'Vengeance Weapon 2'), with the technical name Aggregat 4 (A4), was the world's first long-range [4] guided ballistic missile. The missile, powered by a liquid-propellant rocket engine, was developed during the Second World War in Nazi Germany as a "vengeance weapon" and assigned to attack ...
Fieseler Fi 103 (V-1 flying bomb) The Fieseler Fi 103R, code-named Reichenberg, was a German manned version of the V-1 flying bomb (more correctly known as the Fieseler Fi 103). It was developed towards the end of the Second World War and was intended to be used as a human-guided bomb in likely-suicidal attacks against the advancing Allies.
The special theory of relativity, formulated in 1905 by Albert Einstein, implies that addition of velocities does not behave in accordance with simple vector addition.. In relativistic physics, a velocity-addition formula is an equation that specifies how to combine the velocities of objects in a way that is consistent with the requirement that no object's speed can exceed the speed of light.
The first and second prototypes (Ju 287 V1 and V2; both designated Ju 288 V201 and Ju 288 V202 for security reasons) were intended to evaluate the concept, with V1 being intended to test the FSW and V2 being earmarked for evaluating flight at high subsonic speeds, and both were assembled from the fuselages of the He 177 A-3, the tail of the Ju ...
