Dart (rocket)
A dart is a free flying top of a sounding rocket, and contains the payload. Its form is very aerodynamically designed. After the launch stage burned out the dart is detached and continues to rise only with its own inertia. Some sounding rockets are available both with or without dart. The version without dart is able to transport more payload, but reaches lesser height.

Sounding Rocket
A sounding rocket or rocketsonde, sometimes called a research rocket or a suborbital rocket, is an instrument-carrying rocket designed to take measurements and perform scientific experiments during its sub-orbital flight. The rockets are used to launch instruments from 48 to 145 km (30 to 90 miles) above the surface of the Earth, the altitude generally between weather balloons and satellites; the maximum altitude for balloons is about 40 km (25 miles) and the minimum for satellites is approximately 121 km (75 miles). Certain sounding rockets have an apogee between 1,000 and 1,500 km (620 and 930 miles), such as the Black Brant X and XII, which is the maximum apogee of their class. Sounding rockets often use military surplus rocket motors. NASA routinely flies the Terrier Mk 70 boosted Improved Orion, lifting 270–450-kg (600–1,000-pound) payloads into the exoatmospheric region between 97 and 201 km (60 and 125 miles).

Payload (air And Space Craft)
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. The ...

Aerodynamics
Aerodynamics, from grc, ἀήρ ''aero'' (air) + grc, δυναμική (dynamics), is the study of the motion of air, particularly when affected by a solid object, such as an airplane wing. It involves topics covered in the field of fluid dynamics and its subfield of gas dynamics. The term ''aerodynamics'' is often used synonymously with gas dynamics, the difference being that "gas dynamics" applies to the study of the motion of all gases, and is not limited to air. The formal study of aerodynamics began in the modern sense in the eighteenth century, although observations of fundamental concepts such as aerodynamic drag were recorded much earlier. Most of the early efforts in aerodynamics were directed toward achieving Aircraft#Heavier than air – aerodynes, heavier-than-air flight, which was first demonstrated by Otto Lilienthal in 1891. Since then, the use of aerodynamics through mathematical analysis, empirical approximations, wind tunnel experimentation, and computer simu ...

Inertia
Inertia is the idea that an object will continue its current motion until some force causes its speed or direction to change. The term is properly understood as shorthand for "the principle of inertia" as described by Newton in his first law of motion. After some other definitions, Newton states in his first law of motion: The word "perseveres" is a direct translation from Newton's Latin. Other, less forceful terms such as "to continue" or "to remain" are commonly found in modern textbooks. The modern use follows from some changes in Newton's original mechanics (as stated in the ''Principia'') made by Euler, d'Alembert, and other Cartesians. The term inertia comes from the Latin word ''iners'', meaning idle, sluggish. The term inertia may also refer to the resistance of any physical object to a change in its velocity. This includes changes to the object's speed or direction of motion. An aspect of this property is the tendency of objects to keep moving in a straight li ...

Mohr Rocket
The Mohr Rocket was a sounding rocket developed by Ernst Mohr in Wuppertal Wuppertal (; "''Wupper Dale''") is, with a population of approximately 355,000, the seventh-largest city in North Rhine-Westphalia as well as the 17th-largest city of Germany. It was founded in 1929 by the merger of the cities and tow ..., Germany. It was a single stage solid fuel rocket with: *a length of 1.7 metres, *a total mass of 150 kg (75 kg propellant), *a lift-off thrust of 76.5 kN and a diameter of 0.3 m. *a payload, which could weigh up to 5 kg (this was stored in a dart with a mass of 15 kg, a maximum diameter of 0.056 metre and a length of 1.25 metres.) The burn time of the engine was 2 seconds. After the burnout of the engine the dart was separated from the rocket. Dart and rocket had a height of 1200 m and a speed of 1200 m/s when separated after burnout. The dart flew without further propulsion up to a height of 50 kilometres, because of its ...

MMR06
The MMR06 is a Russian rocket for meteorological experiments, with a length of 3.48 metres and a total weight of 130 kg. The MMR06 rocket was built in two versions: One version had a conical top, the second one, named MMR06-M, had a detachable free flying top, also called dart. The maximum flight height was about 60 - 80 kilometres. Between 1988 and 1992 62 rockets of the type MMR06-M were launched from the former NVA exercise area Zingst, in order to accomplish wind and temperature measurements in the upper atmosphere.

Hopi Dart
Hopi-Dart was an American sounding rocket used by the NASA Marshall Space Flight Center for aeronomy studies in the early 1960s. Design Hopi-Dart was a two-stage vehicle, combining a solid-fuelled Hopi III first stage with an unpowered Dart second stage. It was originally capable of carrying a payload of to an apogee of ; an upgrade, sometimes known as "Hopi Plus", increased the apogee to .Jacobs and Whitney 1962, p. 80.

Loki (rocket)
Loki, officially designated 76mm HEAA Rocket T220, was an American unguided anti-aircraft rocket based on the German Taifun. Like the Taifun, Loki never saw service in its original role, but later found widespread use as a sounding rocket. It was so successful in this role that several advanced versions were developed on the basic Loki layout, including the final Super Loki. Development As part of their anti-aircraft development program of 1942, the ''Luftwaffe'' began developing a number of guided missile projects. However, there was concern that these would not develop in time to be useful in the 1943/44 time frame. To fill the gap, Klaus Scheufelen suggested building a simple unguided rocket that would be fired en-masse directly up into the bomber streams. The result was the Taifun. Taifun was powered by a hypergolic mixture pressure-fed into the combustion chamber. The pressure was provided by small cordite charges that were fired into the fuel tanks, in the process burs ...

Meteor (rocket)
Meteor is a designation of a series of Polish sounding rockets. The Meteor rockets were built between 1963 and 1974. Meteor was the one and two stages meteorological rockets, using the solid fuel, constructed for the research of the top layers of terrestrial atmosphere, also directions and forces of winds from 18 to more than 50 km above the Earth surface. These rockets were designed by Polish engineers of Warsaw Aviation Institute (among them was Professor Jacek Walczewski and engineer Adam Obidziński) and had been produced by WZK-Mielec factory. History The first launching site of the sounding rockets in Poland was Błędowska Desert, where since 1958 to 1963, the rockets of different types had been launched; among others RD and Rasko. During a flight, the biological experiment with earlier trained two white mouses was conducted (the RM-2D rocket achieved the altitude of 1580 meters). Since 1965 to April 1970, the Meteor-1 rockets had been launched from "spaceport" ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
