OBJECTIVES

The recovery and return to base (RRTB) project objectives are:

To validate the reentry of the first stage of the MESO microlauncher
To study and test the novel EDF landing system
To develop robust and cost effective reusable load-bearing structural systems & cryogenic tanks

The RRTB consortium believes that a tailored service for access to space for small satellites is required. However, micro-launchers regularly have higher launch costs per kilogram than bigger launchers. Today, the cornerstone of this emerging market is the economic viability of launching small payloads at high frequencies to dedicated orbits. According to the RRTB consortium, technological development and vehicle reuse are fundamental steps to bring down the cost of launch and access-to-space.

According to the RRTB consortium, technological development and vehicle reuse are fundamental steps to bring down the cost of launch and access-to-space.

This project investigates the recovery and return to base system (RRTB) for the first stage of the MESO launch vehicle. The recovery and return to base system is divided into two parts:

ATMOSPHERIC REENTRY:
The atmospheric reentry of the first stage is one of the most difficult stages for recovering a launch vehicle. Several first stage re-entry configurations will be studied and the most promising one will be validated. The GNC systems will be developed for the chosen re-entry configuration.
LANDING:
Landing of the first stage of the vehicle is intended to be performed using a novel patent pending horizontal landing technology that uses electric ducted fans situated in both sides of the first stage of the launch vehicle to brake the fall of first stage, control it and perform a safe landing.

Furthermore during the project the structural design and analysis of the MESO launch vehicle, as well as an investigation of the launch vehicle’s propellant tanks (a critical component for cost-efficient reuse), will be performed.

The whole system will be designed to be cost-effective and the main driver will be to create a system that is as close as possible to a refuel-and-go refurbishment process. Last, but not least, an economical reusability analysis, including the analysis of the refurbishment procedures, will be performed during the last year of the project.”
