This would eliminate the need for most of the large amount of fuel now needed for delivering a spacecraft into the desired orbit around Mars.) Into 300 x 300 km Venus orbit with same launch vehicle, Aerocapture delivers: • 1.8x more mass into orbit than aerobraking • 6.2x more mass into orbit than all chemical 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. Aerobraking vs Aerocapture Aerocapture Orbit Insertion Burn Atmospheric Drag Reduces Orbit Period Many Passes Through Upper Atmosphere Hyperbolic Approach Aerobraking Energy dissipation/ Autonomous guidance Target orbit Periapsis raise maneuver (propulsive) Entry targeting burn Jettison Aeroshell Aerocapture: A vehicle uses active control to autonomously guide itself 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.

While aerocapture is used for inserting a spacecraft into orbit from a hyperbolic trajectory, aerobraking is used for reducing the apoapsis of a spacecraft that is already in orbit. 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 at Mars, guided ballute aerocapture at Neptune, and aerobraking at Venus. 3.1 Aerocapture HyperPASS performs guided aerocapture simulations by choosing an optimal entry FPA and guiding the vehicle through a bank-modulated aerocapture, in order to achieve the desired exit conditions. The following What does aerocapture mean? A form of aerobraking in which no initial orbit-injection burn is performed. Instead, the spacecraft plunges deeply into Examples of how to use “aerocapture” in a sentence from the Cambridge Dictionary Labs Aerobraking vs Aerocapture.
