A hypergolic propellant is a rocket propellant combination used in a rocket engine, whose components spontaneously ignite when they come into contact with each other. The two propellant components usually consist of a fuel and an oxidizer. The main advantages of hypergolic propellants are that they can be stored as liquids at room temperature ...
Proboscidea louisianica is a species of flowering plant in the family Martyniaceae. Its true native range is unclear, but probably includes parts of the southwestern United States and Mexico in North America. [1] It occurs in other areas, including other regions in North America, [1] Europe, Australia, and South Africa, as an introduced species ...
The electric-pump-fed engine is a bipropellant rocket engine in which the fuel pumps are electrically powered, and so all of the input propellant is directly burned in the main combustion chamber, and none is diverted to drive the pumps. This differs from traditional rocket engine designs, in which the pumps are driven by a portion of the input ...
Figure 1: A de Laval nozzle, showing approximate flow velocity increasing from green to red in the direction of flow. Density flow in a nozzle. A rocket engine nozzle is a propelling nozzle (usually of the de Laval type) used in a rocket engine to expand and accelerate combustion products to high supersonic velocities.
A liquid-propellant rocket or liquid rocket uses a rocket engine burning liquid propellants. (Alternate approaches use gaseous or solid propellants.) Liquids are desirable propellants because they have reasonably high density and their combustion products have high specific impulse (Isp). This allows the volume of the propellant tanks to be ...
Thrust vectoring. Thrust vectoring, also known as thrust vector control (TVC), is the ability of an aircraft, rocket or other vehicle to manipulate the direction of the thrust from its engine (s) or motor (s) to control the attitude or angular velocity of the vehicle. [1][2][3] In rocketry and ballistic missiles that fly outside the atmosphere ...
Rocket Lab Electron. Electron is a two-stage, partially reusable orbital launch vehicle developed by Rocket Lab, an American aerospace company with a wholly owned New Zealand subsidiary. [ 14 ][ 15 ] Electron services the commercial small satellite launch market. [ 16 ] It's the third most launched small-lift launch vehicle in history.
Eruca vesicaria is an annual plant [5] growing to 20 to 100 cm (8 to 40 in) in height. The pinnate leaves are deeply lobed with four to ten, small, lateral lobes and a large terminal lobe. The flowers are 2 to 4 cm (⁄ to 1⁄ in) in diameter, arranged in a corymb, with the typical Brassicaceae flower structure.
