Aggregate Series
The Aggregat series (German for "Aggregate") was a set of ballistic missile designs developed in 1933–1945 by a research program of Nazi Germany's Armed Forces (Wehrmacht). Its greatest success was the A4, more commonly known as the V-2. A1 (1933) The A1 was the first rocket design in the Aggregat series. It was designed in 1933 by Wernher von Braun in a German armed forces research program at Kummersdorf headed by Walter Dornberger. The A1 was the grandfather of most modern rockets. The rocket was long, in diameter, and had a takeoff weight of . The engine, designed by Arthur Rudolph, used a pressure-fed rocket propellant system burning ethanol and liquid oxygen, and produced 2.9 kN (660 lbf) of thrust for 16 seconds. The LOX tank was located within the fuel tank and insulated with a fiberglass material. The rocket was stabilized by a 3 axes gyroscope system in the nose, supplied by Kreiselgeräte G.m.b.H. The rocket could not be rotated for stability as with a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hangar
A hangar is a building or structure designed to hold aircraft or spacecraft. Hangars are built of metal, wood, or concrete. The word ''hangar'' comes from Middle French ''hanghart'' ("enclosure near a house"), of Germanic origin, from Frankish *''haimgard'' ("home-enclosure", "fence around a group of houses"), from *''haim'' ("home, village, hamlet") and ''gard'' ("yard"). The term, ''gard'', comes from the Old Norse ''garðr'' ("enclosure, garden"). Hangars are used for protection from the weather, direct sunlight and for maintenance, repair, manufacture, assembly and storage of aircraft. History The Wright brothers stored and repaired their aircraft in a wooden hangar constructed in 1902 at Kill Devil Hills in North Carolina for their glider. After completing design and construction of the ''Wright Flyer'' in Ohio, the brothers returned to Kill Devil Hills only to find their hangar damaged. They repaired the structure and constructed a new workshop while they waited for th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Walter Dornberger
Major-General Dr. Walter Robert Dornberger (6 September 1895 – 26 June 1980) was a German Army artillery officer whose career spanned World War I and World War II. He was a leader of Nazi Germany's V-2 rocket programme and other projects at the Peenemünde Army Research Centre. Dornberger was born in Gießen and enlisted in 1914. In October 1918, as an artillery lieutenant Dornberger was captured by United States Marines and spent two years in a French prisoner of war camp, mostly in solitary confinement because of repeated escape attempts. In the late 1920s, Dornberger completed an engineering course with distinction at the Berlin Technical Institute, and in the Spring of 1930,Dornberger's detailed account of the V2 project was one of the first to be published by a major participant. Dornberger graduated after five years with an MS degree in mechanical engineering from the '' Technische Hochschule Charlottenburg'' in Berlin. In 1935, Dornberger received an honorary doc ...

List Of Stoffs
During World War II, Germany fielded many aircraft and rockets whose fuels, and oxidizers, were designated (letter)-''Stoff'' (). The following list of stoffs refers to the World War II aerospace meanings if not noted otherwise. Meaning of ''stoff'' The German word ''Stoff'' (plural ''Stoffe''), like the English word ''stuff'', derives from Old French ''estoffe'', however the meanings are somewhat different. Stoff has a fairly broad range of meanings, including "chemical substance" or "matter", "fuel" and "cloth", depending on the context. The German names of the common elements hydrogen, oxygen and nitrogen are ''Wasserstoff'', ''Sauerstoff'' and ''Stickstoff'' ("hydrogen" being a scientific Greek neologism for "constituent of water", "oxygen" for "constituent of acids", "nitrogen" for "constituent of nitre", i.e. saltpeter - although the German root ''stick-'' is derived from ''ersticken'', "to smother, suffocate", referring to its property of not supporting combustion and res ...

Liquid Oxygen
Liquid oxygen—abbreviated LOx, LOX or Lox in the aerospace, submarine and gas industries—is the liquid form of molecular oxygen. It was used as the oxidizer in the first liquid-fueled rocket invented in 1926 by Robert H. Goddard, an application which has continued to the present. Physical properties Liquid oxygen has a pale blue color and is strongly paramagnetic: it can be suspended between the poles of a powerful horseshoe magnet. Liquid oxygen has a density of , slightly denser than liquid water, and is cryogenic with a freezing point of and a boiling point of at . Liquid oxygen has an expansion ratio of 1:861 under and , and because of this, it is used in some commercial and military aircraft as a transportable source of breathing oxygen. Because of its cryogenic nature, liquid oxygen can cause the materials it touches to become extremely brittle. Liquid oxygen is also a very powerful oxidizing agent: organic materials will burn rapidly and energetically in liquid o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Countdown
A countdown is a sequence of backward counting to indicate the time remaining before an event is scheduled to occur. NASA commonly employs the terms "L-minus" and "T-minus" during the preparation for and anticipation of a rocket launch, and even "E-minus" for events that involve spacecraft that are already in space, where the "T" could stand for "Test" or "Time", and the "E" stands for "Encounter", as with a comet or some other space object. Other events for which countdowns are commonly used include the detonation of an explosive, the start of a race, the start of the New Year, or any anxiously anticipated event. An early use of a countdown once signaled the start of a Cambridge University rowing race. One of the first known associations with rockets was in the 1929 German science fiction movie ''Frau im Mond'' (English: ''Woman in the Moon'') written by Thea von Harbou and directed by Fritz Lang in an attempt to increase the drama of the launch sequence of the story's lunar-bo ...

Ammeter
An ammeter (abbreviation of ''Ampere meter'') is an instrument used to measure the current in a circuit. Electric currents are measured in amperes (A), hence the name. For direct measurement, the ammeter is connected in series with the circuit in which the current is to be measured. An ammeter usually has low resistance so that it does not cause a significant voltage drop in the circuit being measured. Instruments used to measure smaller currents, in the milliampere or microampere range, are designated as ''milliammeters'' or ''microammeters''. Early ammeters were laboratory instruments that relied on the Earth's magnetic field for operation. By the late 19th century, improved instruments were designed which could be mounted in any position and allowed accurate measurements in electric power systems. It is generally represented by letter 'A' in a circuit. History The relation between electric current, magnetic fields and physical forces was first noted by Hans Christian Ør ...

Voltmeter
A voltmeter is an instrument used for measuring electric potential difference between two points in an electric circuit. It is connected in parallel. It usually has a high resistance so that it takes negligible current from the circuit. Analog voltmeters move a pointer across a scale in proportion to the voltage measured and can be built from a galvanometer and series resistor. Meters using amplifiers can measure tiny voltages of microvolts or less. Digital voltmeters give a numerical display of voltage by use of an analog-to-digital converter. Voltmeters are made in a wide range of styles, some separately powered (e.g. by battery), and others powered by the measured voltage source itself. Instruments permanently mounted in a panel are used to monitor generators or other fixed apparatus. Portable instruments, usually equipped to also measure current and resistance in the form of a multimeter, are standard test instruments used in electrical and electronics work. Any measurem ...
