Advanced Combustion via Microgravity Experiments (ACME)

The ACME’s Quad Chart provides an overview of the study’s technical scope.

ACME is focused on advanced combustion technology via fundamental microgravity research. The primary goal is to improve efficiency and reduce pollutant emission in practical terrestrial combustion. A secondary objective is fire prevention, especially for spacecraft.

Currently, ACME includes five independent experiments (see ACME Experiments below) investigating laminar, gaseous, non-premixed flames.

The ACME experiments will be conducted with a single modular set of hardware (see ACME Implementation) in the Combustion Integrated Rack (CIR) on the International Space Station (ISS).

An ACME precursor, Structure & Liftoff In Combustion Experiment (SLICE), was conducted in the ISS’ Microgravity Science Glovebox (MSG) in early 2012.

The ACME design is complete and the engineering hardware is being assembled for integrated testing. On-orbit testing is expected to begin in 2017 and continue for a few years.

February 2020 900 Space Flames: Testing for the Advanced Combustion via Microgravity Experiments (ACME, project is underway on the International Space Station.  In the past 2.25 years, over 900 flames have been ignited for the CLD Flame, E-FIELD Flames, BRE, Flame Design, and … Read the rest ⇢


The Advanced Combustion via Microgravity Experiments (ACME) project includes six independent experiments investigating laminar gaseous non-premixed flames. In other words, the flow is smooth and without vortices, the fuel is a gas (and not a liquid or solid), and the fuel and oxygen are not mixed in the burner (but are instead on opposite sides … Read the rest ⇢

Benefits & Relevance

In the United States, nearly 70% of our electrical energy is generated through the combustion of fossil fuels. For example, in 2012, electricity was generated in the U.S. by burning the following fuels, where the percentages indicate the fraction of the total U.S. electrical generation: coal (37%), natural gas (30%), biomass (1.4%), and petroleum (1%). … Read the rest ⇢
