Regener-Tonne
The Regener barrel ( de , Regener-Tonne) was the name of a scientific payload for the World War II V-2 rocket. Mid-1942 plans for subsequent launches to study upper-atmospheric guidance and science were not carried out due to the need for test launches and the eventual advance of the Russian armies. The first meeting was held on July 8, 1942, at the Peenemünde Army Research Station under the direction of Wernher von Braun with the participation of Erich Regener, Ernst Steinhoff, Gerhard Reisig, Helmut Gröttrup, Alfred Ehmert, and Erwin Schopper, among others. Wernher von Braun also tried to win Manfred von Ardenne for cooperation, but he declined. Instrumentation had been contracted on July 11, 1942; and the Research Foundation for the Physics of the Stratosphere was to develop the "Regener barrel" with a quartz barograph, a recording thermometer, an ultraviolet spectrograph, and an air sampler. By January 18, 1945, rumors of nearby Soviet tanks resulted in Erich Regener's or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Erich Regener
Erich Rudolf Alexander Regener (12 November 1881 – 27 February 1955) was a German physicist known primarily for the design and construction of instruments to measure cosmic ray intensity at various altitudes. He is also known for predicting a cosmic background radiation, for the invention of the scintillation counter which contributed to the discovery of the structure of the atom, for his calculation of the charge of an electron and for his early work on atmospheric ozone. He is also credited with the first use of rockets for scientific research. Regener was born in Schleusenau (Wilczak) near Bromberg (Bydgoszcz), West Prussia. He studied physics from 1900 to 1905 at the University of Berlin under Emil Warburg and from 1909 worked with Heinrich Rubens. In 1911 he became professor of experimental physics and meteorology at the Agricultural University of Berlin. In 1920 he became the professor in experimental physics at the University of Stuttgart working alongside the theo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Payload
Payload is the object or the entity which is being carried by an aircraft or launch vehicle. Sometimes payload also refers to the carrying capacity of an aircraft or launch vehicle, usually measured in terms of weight. Depending on the nature of the flight or mission, the payload of a vehicle may include cargo, passengers, flight crew, munitions, scientific instruments or experiments, or other equipment. Extra fuel, when optionally carried, is also considered part of the payload. In a commercial context (i.e., an airline or air freight carrier), payload may refer only to revenue-generating cargo or paying passengers. A payload of ordnance carried by a combat aircraft is sometimes alternatively referred to as the aircraft's warload. For a rocket, the payload can be a satellite, space probe, or spacecraft carrying humans, animals, or cargo. For a ballistic missile, the payload is one or more warheads and related systems; their total weight is referred to as the throw-weight. Th ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
V-2 Rocket
The V-2 (german: Vergeltungswaffe 2, lit=Retaliation Weapon 2), with the technical name ''Aggregat 4'' (A-4), was the world’s first long-range 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 Allied cities as retaliation for the Allied bombings of German cities. The rocket also became the first artificial object to travel into space by crossing the Kármán line (edge of space) with the vertical launch of MW 18014 on 20 June 1944. Research into military use of long-range rockets began when the graduate studies of Wernher von Braun attracted the attention of the Wehrmacht. A series of prototypes culminated in the A-4, which went to war as the . Beginning in September 1944, over 3,000 were launched by the Wehrmacht against Allied targets, first London and later Antwerp and Liège. According to a 2011 BBC documentary, the attacks from r ...

Career Early years The stormy life of von Ardenne's grandmother, Elisabeth von Ardenne (1853–1952), is said to have been be the inspiration for ''Effi Briest'' by Theodor Fontane, one of the most famous German realist novels. Born in 1907 in Hamburg to a wealthy aristocratic family, Ardenne was the oldest of five children. In 1913, Ard ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barograph
A barograph is a barometer that records the barometric pressure over time in graphical form. This instrument is also used to make a continuous recording of atmospheric pressure. The pressure-sensitive element, a partially evacuated metal cylinder, is linked to a pen arm in such a way that the vertical displacement of the pen is proportional to the changes in the atmospheric pressure. Development Alexander Cumming, a watchmaker and mechanic, has a claim to having made the first effective recording barograph in the 1760s using an aneroid cell.Gloria Clifton (2004)"Cumming, Alexander (1731/2–1814)", ''Oxford Dictionary of National Biography'', Oxford University Press. (Subscription or UK public library membership required) Cumming created a series of barometrical clocks, including one for King George III. However, this type of design fell out of favour. Since the amount of movement that can be generated by a single aneroid is minuscule, up to seven aneroids (so called Vidie-cans ...

Recording Thermometer
A recording thermometer is a type of thermometer that records temperature changes over a period of time. A digital recording thermometer is often called a temperature data logger. Analog temperature recorders A type of chart recorder, one end of a bi-metallic strip is attached to a long, light metal lever that holds a special pen. Tiny movements of the bimetallic strip cause much larger movements of the free end of the lever and the pen. The pen traces a rising and falling line on a strip of paper attached to a slowly turning drum. The drum usually makes one turn every seven or so days, so afterward each strip of paper contains a complete and accurate record of temperature changes for a whole week. The bimetallic strip is usually made from steel and copper. Because these metals expand and contract at different rates. When one of these metals expand it curls tighter, when one contracts it uncurls slightly. When it curls or uncurls, the data is converted into electric signals, which ...

Spectrograph
An optical spectrometer (spectrophotometer, spectrograph or spectroscope) is an instrument used to measure properties of light over a specific portion of the electromagnetic spectrum, typically used in spectroscopic analysis to identify materials. The variable measured is most often the light's intensity but could also, for instance, be the polarization state. The independent variable is usually the wavelength of the light or a unit directly proportional to the photon energy, such as reciprocal centimeters or electron volts, which has a reciprocal relationship to wavelength. A spectrometer is used in spectroscopy for producing spectral lines and measuring their wavelengths and intensities. Spectrometers may operate over a wide range of non-optical wavelengths, from gamma rays and X-rays into the far infrared. If the instrument is designed to measure the spectrum on an absolute scale rather than a relative one, then it is typically called a spectrophotometer. The majority o ...
