A Common Food Emulsifier Could Solve One of Rocketry’s Oldest Fuel Problems

In propulsion system design, engineers have long faced a trade-off between solid and liquid rocket fuels. Each has advantages and disadvantages, and in an effort to try to min/max the efficacy of different types of fuel, researchers have long placed an emphasis on a hybrid between solids and liquids – in other words they’ve been working with gels.
