TEPREL
TEPREL is a family of rocket engines designed and built by the Spanish aerospace company PLD Space for their Miura 1 and Miura 5 launch vehicles. The TEPREL engine, named after the Spanish reusable engine program that is financing its development, uses kerosene and liquid oxygen as propellants. So far, several versions of this engine, intended to propel Miura 1, have been developed and tested on the company's own liquid propulsion test facilities located in Teruel, Spain. Revisions In the first versions of the engine the propellants are driven to the engine by using a pressure-fed cycle with helium. Later versions of the engine (TEPREL-C) incorporate a turbopump. TEPREL-DEMO The TEPREL-DEMO engine, originally called NetonVac1, was first tested in 2015. It is a calorimetric engine model, intended to demonstrate combustion stability as well as to acquire relevant information such as ignition and shut-down sequences, pressures and temperatures along the engine, thrust and propel ...

PLD Space
Payload Aerospace S.L. (PLD Space) is a Spanish company developing two partially-reusable launch vehicles called Miura 1 and Miura 5. Miura 1 is designed as a sounding rocket for sub-orbital flights to perform research or technology development in microgravity environment and/or in the upper atmosphere. Furthermore, Miura 1 is also serving as the technological demonstrator of the orbital launcher Miura 5. Miura 5 will provide orbital launch capabilities for small payloads such as CubeSats, that need a flexible and dedicated launch vehicle and therefore can not fly with traditional launch vehicles. It is being designed to deliver a total payload mass up to into low Earth orbit. Recovery of the first stage would be by the use of parachutes and splashdown for re-use. History PLD Space was founded in 2011 by Raúl Torres, Raúl Verdú and José E. Martínez in Elche, Spain, and as of 2019 it employs 70 people. In August 2017 the company headquarter moved to new facilities in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miura 5
Miura 5 is a two-stage European orbital recoverable launch vehicle of the Spanish company PLD Space currently under development. Miura 5 will be 24.9 m long, capable of inserting 900 kg of payload into a low Earth orbit (LEO), featuring an optional kick stage that can circularize the orbits of satellites. All stages are planned to be liquid-propelled. The launch vehicle was previously called ''Arion 2'' but in 2018 PLD Space changed its name. Design The two stages (expandable to 3) of the Miura 5 are planned to use liquid fuel and are designed to reuse most of the technology developed for Miura 1, being the new engine and propellant tanks. The first stage is planned to be reusable through the combined use of its engines and parachutes for retrieval. The Miura 5 will use a TEPREL-C turbopump engine, unlike previous versions which use a pressurized tank cycle. A lift capacity of 150 kilograms was originally envisioned, but in 2018 lift capacity was doubled after a 10-m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miura 1
Miura 1 (previously called Arion 1) is a suborbital recoverable launch vehicle developed by the Spanish company PLD Space. It is planned to be the first recoverable launch vehicle in Europe. The first launch is currently scheduled for the 15 January 2023. Design Miura 1 was originally proposed as a two-stage rocket capable of achieving suborbital flight. It was originally planned to be 12 m long, with a capacity of 250 kg (551 lb). The engines were to use liquid oxygen and kerosene as propellants. In its final design, Miura 1 is a 12.7 m long 0.7 m diameter one-stage rocket, propelled by one TEPREL-B engine. The vehicle can fly a payload of up to 200 kg on a suborbital trajectory. The propulsion system is equipped with actuators to tilt the engine for an active thrust vector control. In its first mission it will carry 100 kg of payload to an apogee of 153 km. Additionally, Miura 1 is equipped with a recovery system using its engines and parachutes that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spacecraft Propulsion
Spacecraft propulsion is any method used to accelerate spacecraft and artificial satellites. In-space propulsion exclusively deals with propulsion systems used in the vacuum of space and should not be confused with space launch or atmospheric entry. Several methods of pragmatic spacecraft propulsion have been developed each having its own drawbacks and advantages. Most satellites have simple reliable chemical thrusters (often monopropellant rockets) or resistojet rockets for orbital station-keeping and some use momentum wheels for attitude control. Soviet bloc satellites have used electric propulsion for decades, and newer Western geo-orbiting spacecraft are starting to use them for north–south station-keeping and orbit raising. Interplanetary vehicles mostly use chemical rockets as well, although a few have used ion thrusters and Hall-effect thrusters (two different types of electric propulsion) to great success. Hypothetical in-space propulsion technologies describe the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rocket Engines Using Kerosene Propellant
A rocket (from it, rocchetto, , bobbin/spool) is a vehicle that uses jet propulsion to accelerate without using the surrounding air. A rocket engine produces thrust by reaction to exhaust expelled at high speed. Rocket engines work entirely from propellant carried within the vehicle; therefore a rocket can fly in the vacuum of space. Rockets work more efficiently in a vacuum and incur a loss of thrust due to the opposing pressure of the atmosphere. Multistage rockets are capable of attaining escape velocity from Earth and therefore can achieve unlimited maximum altitude. Compared with airbreathing engines, rockets are lightweight and powerful and capable of generating large accelerations. To control their flight, rockets rely on momentum, airfoils, auxiliary reaction engines, gimballed thrust, momentum wheels, deflection of the exhaust stream, propellant flow, spin, or gravity. Rockets for military and recreational uses date back to at least 13th-century China. Signific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nozzle
A nozzle is a device designed to control the direction or characteristics of a fluid flow (specially to increase velocity) as it exits (or enters) an enclosed chamber or pipe. A nozzle is often a pipe or tube of varying cross sectional area, and it can be used to direct or modify the flow of a fluid (liquid or gas). Nozzles are frequently used to control the rate of flow, speed, direction, mass, shape, and/or the pressure of the stream that emerges from them. In a nozzle, the velocity of fluid increases at the expense of its pressure energy. Types Jet A gas jet, fluid jet, or hydro jet is a nozzle intended to eject gas or fluid in a coherent stream into a surrounding medium. Gas jets are commonly found in gas stoves, ovens, or barbecues. Gas jets were commonly used for light before the development of electric light. Other types of fluid jets are found in carburetors, where smooth calibrated orifices are used to regulate the flow of fuel into an engine, and in jacuzzis or spa ...

Regenerative Cooling (rocket)
Regenerative cooling, in the context of rocket engine design, is a configuration in which some or all of the propellant is passed through tubes, channels, or in a jacket around the combustion chamber or nozzle to cool the engine. This is effective because the propellants are often cryogenic. The heated propellant is then fed into a special gas-generator or injected directly into the main combustion chamber. History In 1857 Carl Wilhelm Siemens introduced the concept of regenerative cooling. On 10 May 1898, James Dewar used regenerative cooling to become the first to statically liquefy hydrogen. The concept of regenerative cooling was also mentioned in 1903 in an article by Konstantin Tsiolkovsky. Robert Goddard built the first regeneratively cooled engine in 1923, but rejected the scheme as too complex. A regeneratively cooled engine was built by the Italian researcher, Gaetano Arturo Crocco in 1930. The first Soviet engines to employ the technique were Fridrikh Tsander's OR-2 ...

Combustion Chamber
A combustion chamber is part of an internal combustion engine in which the fuel/air mix is burned. For steam engines, the term has also been used for an extension of the firebox which is used to allow a more complete combustion process. Internal combustion engines In an internal combustion engine, the pressure caused by the burning air/fuel mixture applies direct force to part of the engine (e.g. for a piston engine, the force is applied to the top of the piston), which converts the gas pressure into mechanical energy (often in the form of a rotating output shaft). This contrasts an external combustion engine, where the combustion takes place in a separate part of the engine to where the gas pressure is converted into mechanical energy. Spark-ignition engines In spark ignition engines, such as petrol (gasoline) engines, the combustion chamber is usually located in the cylinder head. The engines are often designed such that the bottom of combustion chamber is roughly in li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Teruel Airport
Teruel Airport is an airport near Teruel in the Teruel Province of Spain. Known under the commercial name Plataforma Aeroportuaria-Teruel (PLATA), it was certified for public use by the Spanish Aviation Safety and Security Agency (AESA) on 5 February 2013. Permission for air operations was granted by the AESA on 28 February 2013. The airport serves as an aircraft maintenance and aircraft storage facility for the company. PLATA is owned by a consortium formed by the Government of Aragon and Teruel City Council, and does not belong to Aena Group, the Spanish airports management company. The dry climate makes the airport suitable for long-term aircraft storage, with capacity for 250 aircraft. During the COVID-19 pandemic, approximately 100 grounded planes were parked there. The airport includes a main building with a control tower as well as a basic terminal, but is not equipped to handle passenger traffic. An aircraft rescue and firefighting (ARFF) station is located next to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turbopump
A turbopump is a propellant pump with two main components: a rotodynamic pump and a driving gas turbine, usually both mounted on the same shaft, or sometimes geared together. They were initially developed in Germany in the early 1940s. The purpose of a turbopump is to produce a high-pressure fluid for feeding a combustion chamber or other use. There are two types of turbopumps: a centrifugal pump, where the pumping is done by throwing fluid outward at high speed, or an axial-flow pump, where alternating rotating and static blades progressively raise the pressure of a fluid. Axial-flow pumps have small diameters but give relatively modest pressure increases. Although multiple compression stages are needed, axial flow pumps work well with low-density fluids. Centrifugal pumps are far more powerful for high-density fluids but require large diameters for low-density fluids. History Early development High-pressure pumps for larger missiles had been discussed by rocket pioneers su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
