ACME BRE — Advanced Combustion via Microgravity Experiments - Burning Rate Emulator
Hardware: Combustion Integrated Rack (CIR), ACME · Program: International Space Station (ISS) · Fuel phase: Gas · DOI 10.60555/vb93-3y72
Objective
The BRE flight program seeks to establish the burning conditions in a quiescent microgravity ambient in terms of material properties. The specific flight objectives are as follows. 1. Observe burning behavior in long-duration microgravity for CH4/N2 and C2H4/N2mixtures on porous circular burners of 25 and 50 mm diameter. Consider O2/N2 ambients with various pressures and ambient O2 concentrations and pressures. NASA - considered atmosphere for human space missions will be examined: 14.7 psia, 21 % oxygen: 10.2 psia, 26.5 %; and 8.2 psia, 34 % oxygen. Emphasize fuel conditions that can be related to a diverse range of condensed fuels. 2. Consider the conditions of Objective 1 for ambients of O2/CO2 (desired). 3. Consider the conditions of Objectives 1 – 2 for extinction limits.
