Miura 1

Miura 1 (previously called Arion 1)[3][4] is a suborbital recoverable launch vehicle of the Spanish company PLD Space. It is planned to be the first recoverable launch vehicle in Europe.[5] The initial launch has been delayed to 2022.[6]

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.[7]

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.[8] 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 enable PLD Space to recover the vehicle from the ocean and re-use the complete launch vehicle.[9] With this, it will be the first recoverable launch vehicle in Europe.[5] Miura 1 is intended to be used for scientific research or technology development in a microgravity environment and/or in the upper atmosphere. Furthermore, about 70% of the technology developed for Miura 1 is planned to be used on the Miura 5 orbital rocket.[10]

In December 2019 GMV announced that the Miura 1 avionics system had passed the qualification phase[11]

In March 2020, the stress test of the Miura 1 pressurized tanks was carried out to check their ability to withstand the working pressure (more than 400 bars) with a successful result.[12] COPVs (Composite Overwrapped Pressure Vessel) are used to pressurize propellant tanks and are a fundamental element of many launchers.[13]

In July 2020 the German Center of Applied Space Technology and Microgravity (ZARM) successfully completed vibration tests of its payload that will fly on the first launch (Test Flight-1) of Miura 1.[14]

On April 7, 2022, the company carried out the first test of the complete launcher at its facilities in Teruel, being the first test in Europe of a rocket propelled by liquid fuel.[15][16][17]

Launch schedule

The first test flight of Miura 1 was planned for 2021[18] from an experimental rocket launch site in Huelva, southwestern Spain, called El Arenosillo,[19] and it will carry a payload from the German Center of Applied Space Technology and Microgravity (ZARM).[4] Up to eight suborbital launches are targeted per year. It has been delayed to 2022.[6]
