If you have heard a roar at Teruel airport it is because PLD Space has just tested the new Miura 5 rocket engine

A thermal chamber pointing to the test table of PLD Space At Teruel Airport, he has witnessed the first tests of the Treprel-C engine, the heart of the Spanish rocket Miura 5.

Wake up, Miura, wakes up. PLD Space engineers have moved the first engines of the new Treprel-C family to the test zone for a series of integrated hardware trials.

With these tests, the preparations for the flight rating campaign finalize, with which they will valid the design and tolerance of the motor to integrate it into the rest of the rocket. As Pld Space has advanced In his X profilethe new manufacturing technologies of combustion cameras that they have tried have “very good look”.

A jump to the big leagues. The launch of Miura 1 served to validate all kinds of processes and technologies Internally developed, but the Miura 5 engine is much more complex. We talk about a two -stage orbital pitcher, designed to Place satellites of up to a ton In equatorial orbit.

With a height of 35.7 meters, Miura 5 needs five teprel-C engines to rise. The engine is a direct evolution of the technologies validated by Miura 1 with an important qualitative leap: it is a turbobombic fueled engine in which the reliability apart from performance prevails.

Treprel-C. The new Treprel engine (acronym for “Spanish technology for reusable spatial propulsion for pitchers”) generates 190 kn of thrust at sea level: 950 kN in total for the first stage of the Miura 5. The second stage of the rocket carries an optimized version for the vacuum.

These engines, with a height comparable to that of a person, presume to have the combustion chamber of liquid propellant developed by a commercial company with private capital in Europe. They feed on RP-1 bioquerosen and liquid oxygen.

Manufactured in Elche. The new PLD Space plant in Elche, 12,500 square meters, is designed to produce up to six MIURA 5 and 60 Treprel-C motors per year, which gives an idea of ​​the project ambition.

The company’s facilities at Teruel airport have become, since Miura 1, in the epicenter of static tests. At the end of 2024, PLD Space lifted a 20-meter test tower for cryogenic and pressure test tower, and has built a test bench capable of trying three treprel-C simultaneously. The debut of Miura 5 is scheduled for early 2026.
