Distributed optical fibre sensors (DOFS) are highly suitable for monitoring temperature, vibration and strain using physical principles such as Raman, Rayleigh and Brillouin backscatter. They convert a standard telecom infrastructure to a sensor network providing thousands of virtual sensors per km using the intrinsic light/glass interaction during propagation.

GaN-based devices are becoming a key technology for millimeter-wave applications. Because of outstanding material properties, recent advances in GaN device designs provided a sharp increase in performances including high power, high efficiency, reliability, linearity, and compact size. These capabilities are ideally suited for numerous millimeter-wave power applications such as wireless networks and PAs MMIC for Q-band frequency and beyond.

Assembly, Integration, and Testing (AIT) processes occur during the phases C and D of the engineering processes of a given flight vehicle. System integration processes take place at the level of engineering models, structural and thermal models, and qualification models of flight vehicles.The current ATD tools cover the phases 0, A, and part of the phase B (B1) for design, and development of flight vehicles. Beyond those phases, the current toolset is not able to cover tasks of system integration and testing (phases C, D).

The majority of large engine activity in Europe is hydrogen based and requires more costly pump technology, with deep cryogenic temperatures and complex sealing requirements. This activity was to demonstrate a low-cost LOX pump design, manufacture and test capability with view to enabling a LOX Kerosene 60kN engine program. These engines are more appropriate for the small launcher market than LOX/LH2.

Objective:
Demonstrate robust and repeatable vacuum ignition of LOX/Kerosene breadboard ignitor.

Project HyperClass aimed at accelerating the technology to process spectra received from single pixel images of space objects and:

i) extract the material composition of the object,

ii) classify the object according to a set of predefined features,

iii) estimate the attitude motion from the spectral lightcurve.

The objectives of the DONE3D activities are the implementation of a novel additive manufacturing supply chain that is based on the through Lithography Metal Manufacturing (LMM) technology, and to assess its applicability to the development of RF components for SatCom and EO applications, such as multi-beam antennas.

The main objective of the intelligent COTS-based Power Stages (iCOTS) project consisted of the following aspects:

• Design and implementation of a BLDC power stage for robotic space application
• A modular design for the evaluation of power electronics in robotic space application based on COTS GaN-FETs
• Definition of the design process and the appropriate selection of COTS components
• Radiation test of selected COTS components
