Aerocapture demonstration mission

The AERODEM is an ESA demonstration mission that will implement an aerocapture phase in order to provide an atmospheric ∆V instead of a standard chemical one for orbiting a SpaceCraft around Mars. The aerocapture technique currently studied relies on a discrete event drag modulation technique that modifies only once the aerocapture module ballistic coefficient by separating / retracting the heatshield.

Aerocapture demonstration mission

An interplanetary probe must decelerate from a hyperbolic interplanetory trajectory to an orbital trajectory when it arrives at its destination. Currently, this maneuvre is achieved using chemical propulsion, which means that propellant makes up a significant fraction of the vehicle mass. Aerocapture is an alternative concept that instead uses aerodynamic drag from the athmosphere of the planet to decelerate the arriving spacecraft.

Inflatable Systems for Aerocapture and Aerobraking

This work has primarily focused on establishing scenarios where inflatable devices could be the most useful. Given that these missions rely on aerodynamic drag that results in (potentially significant) heating, the authors have sought to find solutions to minimize heat fluxes acting on the device surface, and especially keeping it within the limits of flexible/foldable TPS materials for the aerocapture scenario.
