New hypergolic fuels research Q&A
« on: 07/26/2023 03:31 pm »
An article linked below mentions that a new "green" hypergolic rocket fuel has been developed by a research institute as a part of "10-20N Green Bipropellant Thruster" project by ESA.

One component (oxidizer) is 98% hydrogen peroxide, the other is a substance which is said to be "widely available and used in the industry".
This novel fuel with Isp of 310s was tested in lab using 20N satellite engine for a cumulative time of 2 seconds (the shortest run was 10ms).

Q: could you put this development in the industry context?  (groundbreaking, yawn, one of many such research projects etc)

One of many such projects. There are probably dozens of "green" hypergolic fuels, of various types and chemical constitutions, in various stages of being tested and flown over the past decade or so.

"Green" in this case generally meaning less toxic / safer to handle than hydrazine, which is a fairly low bar, and / or with less harmful combustion byproducts.

Short list of examples:

AF-M315E
FLP-106
LMP-103S
Viscous Liquid Monopropellant (VLM)
