Our countdown includes NASA and Blue Origin replicas as well as Estes models with cameras and STEM sets for kids.

Dubai, UAE — LEAP 71 has announced the next phase of its rocket engine program, scaling its computational engineering methodology to develop meganewton-class propulsion systems ... Large Computational ...

Eventually, a 16-foot-tall model of Blue Origin’s New Glenn rocket will take its place beside the engine. Two BE-3U engines power the upper stage of the New Glenn orbital-class rocket ...

Model rockets, in contrast, generally use solid rocket engines that mix the oxidizer and fuel into a single package, and they are ignited with heat. This makes them shelf-stable and far less ...

So, while you might never get the chance to build a rocket engine on this scale, just looking inside the process is fascinating. Who knows? It might help you with your next model rocket project.

including a custom thrust vectoring mechanism for model rocket engines. Relying on a pair of servo motors that are geared down to improve the accuracy of their movements, the thrust from the ...
