Fire safety in spacecraft: Past incidents and Deep Space challenges

Fire Safety Challenges in Hospital Safety Index (HSI)

Hospitals are a symbol of social welfare and the last refuge of patients, which is the most important issue of the health system. Patient safety is the first and most important issue for the health system.  Before COVID-19, the World Health Organization (WHO) defined the Hospital Safety Index (HSI) to measure hospital preparedness for disasters. During the COVID-19 crisis, hospitals faced many ...

Microgravity Research in Spacecraft Fire Safety

Fire prevention, detection, and suppression requirements for spacecraft have been developed primarily from established terrestrial and aircraft systems aided by the experience gained from previous space operations. However, the most important factor distinguishing spacecraft fire protection from terrestrial systems is the low-gravity environment that dominates fire and particulate behavior and ...

Challenges on Hospital Fire Safety during COVID-19 Crisis

Fire Safety in the Low-Gravity Spacecraft Environment

Research in microgravity (low-gravity) combustion promises innovations and improvements in fire prevention and response for human-crew spacecraft. Findings indicate that material flammability and fire spread in microgravity are significantly affected by atmospheric flow rate, oxygen concentration, and diluent composition. This information can lead to modifications and correlations to standard m...

Deep Space Formation Flying Spacecraft Path Planning

Efficient algorithms for collision-free energy sub-optimal path planning for formations of spacecraft flying in deep space are presented. The idea is to introduce a set of way-points through which the spacecraft are required to pass, combined with parameterizations of the trajectories which are energy-optimal for each spacecraft. The resulting constrained optimization problem is formulated as a...
