ONERA , the French Aerospace Lab, is a public research establishment whose goal is to perform fundamental and applied research to support the competitiveness and creativity of the European aerospace and defense industry. The research carried out at ONERA involves both fundamental activities for mid to long term aerospace applications, and more applied activities, such as the design and manufacturing of prototypes (early warning radars, lightning monitoring network or satellite payload). The laboratory have two teams involved in Plas@Par:
Lightning, Plasma Applications (FPA)
Location: ONERA, PalaiseauA research group in the Physics and Instrumentation Department.
Activities, linked to Plas@Par involve: Lightning: study of lightning interaction on aircraft (strike probability, thermal and mechanical stress on complex structure). Based on medium-scale test facility and numerical modeling, the research aims at understanding the basic phenomena of lightning-aircraft interaction, and to increase aircraft security. In parallel, the team develops sensor networks for lightning activity monitoring (ground station and airborne) and medium scale experiments for plasma-material interaction characterization.
Non-equilibrium plasma for aerospace applications: The growing importance of this topic is spurred by the need of cleaner, leaner airframe. The team experimental and numerical activities are devoted to find novel applications of plasmas in the aerospace industry. For example, such applications are plasma-assisted flow control, plasma assisted combustion, depollution. Plasma for space propulsion: the group has a recognized expertise in electric thruster diagnostics. These diagnostics provide the necessary input to validate the models that are now currently developed to understand the physics of novel plasma thruster concepts and develop new thrusters. The team is also involved in the development of a new electrode-less thruster that does not require beam neutralization.
Spacecraft-Environment Coupling (CSE)
Location: ONERA, Toulouse
A research group of the Space Environment Department Activities, linked to Plas@Par surface interaction phenomena, at the microscopic level, such as secondary electron emission, surface erosion, properties modifications due to radiation and energetic particles, to provide reference data and lumped models for macroscopic simulations.
