COLD REACTION, REUSABLE FIRST STAGES
The EcoRocket uses water-based propulsion technology for its first two stages, that generates water vapours. This is opposite to the current rocket engines that release polluting, toxic, carcinogenic compounds into the atmosphere.
The first stage will reach an altitude of 8,000m and a speed of Mach 1,400km/h.
The second stage will reach an altitude of 50,000m and a speed of Mach 5,600km/h.
The eco-friendly technology was developed at ARCA starting with 2018 and it's called the Launch Assist System (LAS). EcoRocket uses the second generation LAS that has 25% higher specific impulse compared with the first generation.
In February 2019 ARCA started the study of a reusable LAS vehicle using an aerospike engine, with VTOL capability. This was applied to the EcoRocket's first stage, that exhibits a Vertical Take-Off and Landing (VTOL) flight sequence and is completely reusable. More about the LAS technology in this White Paper.
After the first two stages tanks depletion, the hot upper stage will continue the flight to orbit.
The first two stages, will descent to the ground and land in the same launch location.
HOT, EXPANDABLE UPPER STAGE
The EcoRocket's upper stage uses hydrogen peroxide 95% and kerosene. The amount of polluting propellant for the whole rocket is 14% and the third stage ignites above 50km altitude.
The third stage will put a 10kg payload to a circular orbit at 220km altitude.
The EcoRocket flight sequence is presented in this Video.
First orbital launch: September 2021;
Second orbital launch: November 2021;
Start of commercial operations: December 2021.
