LANL scientists test new rocket design flight

-A A +A

Los Alamos National Laboratory scientists recently flight tested a new rocket design that includes a high-energy fuel and a motor design that also delivers a high degree of safety.
“What we’re trying to do is break the performance versus sensitivity curve, and make a rocket that’s both very high-energy, as well as very safe,” said Bryce Tappan, an energetic materials chemist at the laboratory. “Typically, when you look at a propellant that’s high-performance, it’s not as safe a material.” See the flight tests and hear how Tappan and his research partners at New Mexico Tech and Penn State accomplished a fully successful flight in a new video on the laboratory’s YouTube Channel.
Conventional solid-fuel rocket motors work by combining a fuel and an oxidizer, a material usually rich in oxygen, to enhance the burning of the fuel. In higher-energy fuels this mixture can be somewhat unstable, and can contain sensitive high explosives that can detonate under high shock loads, high temperatures, or other conditions.
The new rocket fuel and motor design adds a higher degree of safety by separating the fuel from the oxidizer, both novel formulations that are, by themselves, not able to detonate.
