Abstract

This research explores advancements in braking technology with a focus on enhancing vehicle safety. The topic was chosen due to the critical importance of literature connecting braking technology developments to safety levels. The method employed was a comprehensive review of current literature concerning types and advancements in braking technologies, particularly in automotive vehicles. Analysis indicates that integrating modern braking technologies can significantly enhance driving safety and comfort, although challenges related to costs and maintenance need further attention. Further studies are recommended to optimize the future implementation of these technologies.

Abstract

High-altitude free-flight tests require release mechanisms capable of placing sub-scale re-entry capsules into a clean supersonic freestream while minimizing wake-induced attitude perturbations. This study presents AERO, a compact pneumatic ejection mechanism developed to support NASA SPEED-class capsule-release requirements as a scientific contribution to re-entry testing technology. The method combined wake-clearance interpretation, first-order kinematic sizing, pneumatic force analysis, CAD-based packaging, manufacturability assessment, and scaled prototype testing. A two-projectile-length clearance distance of 1.33 m was adopted, giving a required initial velocity of 5.11 m/s for a 0.5 s separation target. The full-scale analytical model predicted an ejection velocity of 5.2 m/s and a 0.44 s separation time at 0.5 MPa; increasing the operating pressure to 1.5 MPa increased the velocity to 9.7 m/s and reduced the separation time to 0.15 s. A 30% scale prototype using a 32 g Genesis Firefly capsule model showed a pressure-dependent height response, increasing from 63.0 cm at 0.2 MPa to 136.8 cm at 0.6 MPa. These findings provide analytical and scaled-prototype evidence that a pressure-tunable pneumatic architecture with a balancing hugger can support rapid, repeatable, and geometry-adaptable capsule ejection; flight-representative performance remains to be validated.
