DARE’s latest rocket engine additively manufactured as single unit
February 24, 2025
Delft Aerospace Rocket Engineering (DARE), a student rocketry initiative at the Delft University of Technology headquartered in Delft, the Netherlands, has revealed the next iteration of its additively manufactured Firebolt engine, the DLX-150C.
Developed to power DARE’s Stratos V rocket, this regeneratively cooled engine is reported to deliver 9 kN of thrust. With a near-flight-ready design, the DLX-150C is seen as a significant step forward.
Building on the previous DLX-150B, the team removed the film cooling ring and redesigned a significant part of the engine as a single unit. To build the engine, DARE relied on 3D Systems Corporation, headquartered in Rock Hill, South Carolina, USA, whose Additive Manufacturing technology and large build plate size enabled the team to combine the thrust chamber, nozzle, and throat into a single piece.
