We are fascinated by the hybrid rocket engine which [Ben Krasnow] built and tested in his shop. It is actually using a hollow cylinder of acrylic as the fuel, with gaseous oxygen as an oxidizer. We… ...

This design reportedly serves as an effective mitigation strategy against nozzle erosion in hybrid propulsion systems, preventing performance degradation throughout the ascent phase of the flight.

A hybrid rocket propulsion system comprises propellants of two different states of matter, the most common configuration being a rocket engine composed of a solid propellant lining a combustion ...

The first in a series of tests of Bloodhound SSC’s hybrid rocket motor worked pretty much as planned, with a blazing, stable flame emanating from the rocket nozzle. Now the design team will ...

An upgraded version of one of the solid rocket boosters being used for NASA's Space Launch System (SLS) experienced an ...

Hybrid rocket engines offer perks from both worlds, ... Despite this, it’s a great look at nozzle design and all the science involved.

The nozzle’s throat is about 0.25″ and expands to 0.625″. I lit the engine by inserting a burning cotton swab (with wooden stick) while a small amount of oxygen was flowing.

Make A Hybrid Rocket Engine With Pasta, Hydrogen Peroxide, And Yeast. Posted: March 27 ... all sorts of modifications could be made to this experiment to allow throttle control and even a nozzle.

Solid-fuel rockets are great for plenty of things, like boosting Space Shuttles into orbit or launching a hobby rocket into not-quite-orbit-but-way-way-up-there. Of course, if you want a semblance ...

Since at least the 1950s, rocket engineers have wondered whether another nozzle design, known as the aerospike, could be a more efficient way to send humans to the stars.
