Aerocapture is a subcategory of aerobraking. Atmospheric drag is used to reduce velocity to a point the vehicle can enter a stable orbit with a minimum or no propellant burn. Aerocapture can be the prelude to descent and entry into the atmosphere.

Comparison of aerocapture and aerobraking Aerocapture is a lot more challenging, since the deceleration has to take place a lot lower in the atmosphere in order to provide the required deceleration in such a short distance. This implies much higher forces and heat-fluxes, which require some sort of aeroshield/TPS system. Here are a few of the main challenges of aerobraking and aerocapture: 2019-10-07 · Since aerocapture is an orbit insertion maneuver, the atmospheric entry velocities correspond to V ∞ of 0–7.5 km/s, which is similar to the velocity ranges used for entry, but with the exclusion of entry velocities for closed orbits (which is also the range of entry velocities used for aerobraking analysis). Aerocapture maneuver is very sensitive to uncertainties; thus in order to ensure a successful aerocapture maneuver, vehicle control authority is required.

Aerocapture can be the prelude to descent and entry into the atmosphere. Aerobraking is a spaceflight maneuver that reduces the high point of an elliptical orbit by flying the vehicle through the atmosphere at the low point of the orbit. The resulting drag slows the spacecraft. Aerobraking is used when a spacecraft requires a low orbit after arriving at a body with an atmosphere, and it requires less fuel than does the direct use of a rocket engine.

from orbit, aerocapture, aerobraking and aero-gravity assist. This paper’s focus is aerocapture. In an aerocapture manuever, aerodynamic forces are used to decelerate a vehicle from its hyperbolic approach trajectory into a closed orbit about a planet in a single atmospheric pass.

The reduced mission mass results in more available spacecraft resources for the science application at the final destination. The peak heat rate is within the capability of existing thermal protection system materials for both control techniques. Delivered mass fraction using aerocapture is compared with propulsive insertion with and without aerobraking.

Aerocapture is an orbital transfer maneuver used to reduce the velocity of a spacecraft from a hyperbolic trajectory to an elliptical orbit around the targeted celestial body. New!!: Aerobraking and Aerocapture · See more » Aerogravity assist

Aerocapture would enable long term studies of the outer planets and their moons that would not be possible with existing braking technologies. Translations in context of "aerobraking or aerocapture" in English-French from Reverso Context: Special methods such as aerobraking or aerocapture are sometimes used for this final orbital adjustment. aerobraking concept is intrinsically more desirable, from a conceptual viewpoint, than propulsive velocity reductions since this theoretically permits more vehicle weight to be used for payload instead of fuel. The technique of 'aerobraking' uses drag during successive passes through the upper atmosphere to circularize a highly elliptical orbit.
