Real-Time Orbiter Abort Guidance

This paper describes a real-time abort guidance algorithm which determines the time sequence of the powered maneuvers and the orientation of the thrust vector throughout an abort-mission action initiated during the orbiter ascent phase. It involves guiding a heavily loaded Space Shuttle vehicle, passing through severe environmental conditions, back to a designated landing area. A graphical exam...

Capsule Abort Recontact Simulation

A study is performed to ascertain the validity of the use of inviscid and viscous simulation methods to predict the axial and normal forces during a launch abort scenario for manned space flight vehicles. The proximity drag character of the Apollo launch escape vehicle (LEV) was studied in detail in a wind tunnel during the Apollo program. Simulation results obtained during the present effort a...

The Rhic Beam Abort Kicker System*

The energy stored in the RHIC beam is about 200 kJ per ring at design energy and intensity. To prevent quenching of the superconducting magnets or material damage, the beam will be safely disposed of by an internal beam abort system, which includes the kicker magnets, the pulsed power supplies, and the dump absorber. Disposal of heavy ions, such as gold, imposes design constraints more severe t...

Loop-Abort Faults on Supersingular Isogeny Cryptosystems

Cryptographic schemes based on supersingular isogenies have become an active area of research in the field of post-quantum cryptography. We investigate the resistance of these cryptosystems to fault injection attacks. It appears that the iterative structure of the secret isogeny computation renders these schemes vulnerable to loop-abort attacks. Loop-abort faults allow to perform a full key rec...

The Ares I Abort Failure Detection, Notification, and Response System: An Overview of the Development Process

Timely detection and response to catastrophic events during the launch and ascent phase of the Ares I launch system is of paramount importance to crew safety. This requires an abort system capable of detecting and confirming conditions that may lead to catastrophic failure, notifying the crew of the problem, and responding in time to allow the crew to escape safely. The Ares I Abort Failure Det...
