Technological advancements in reusable rocket engine technology

While economic viability is a prime motivator, another crucial factor has been progress on the technological front related to reusable propulsion systems. Reusing rocket stages require that engines themselves should be repeatedly relightable, durable and cause minimum damage during landing and recovery. Engine manufacturers have been steadily enhancing engine designs to meet these challenging requirements. SpaceX's Merlin 1D engine powering Falcon 9 has flown over 100 missions with multiple firings and landings. Various design changes like additively manufactured combustion chambers, optimizations in propellant mixture ratios, use of lightweight materials and advanced health monitoring systems have increased the engine's reliability. IHI, a Japan-based company, similarly developed the LE-7 engine featuring staged combustion cycle for decreased weight and improved reusability suited for future H-3 rockets.

 Developing advanced propellant types to improve engine performance on subsequent flights can also drive the market growth. This includes using non-toxic and storable propellants as opposed to cryogenic and hypergols. Companies like Rocket Lab and Relativity Space are pursuing hydrocarbon fuels owing to their ease of handling. Relativity is also 3D printing entire smallsat launch vehicles with its proprietary additive manufacturing method to make reuse affordable. Supersonic and hypersonic retropropulsion technologies enabling precise rocket landing are also seeing leaps. SpaceX's grid fins, landing legs, landingburn of Falcon 9 and Tesla electric turbo-pumps represent numerous innovations in this regard. Various experimental reusable engine projects have also contributed profoundly to knowledge gain in combustion instability, multi-start capabilities, extended mission durations and health monitoring of components under reuse stresses. Further continued strides are envisioning even more ambitious reusable rocket architectures. These technical evolutions have lent practicality and credence to the reusable launch
