The fuel dispersion system is a critical part of any rocket design. Poor mixing of propellants could result in a major explosion, or inefficiency at best. Consequently we put a whole lot of research into it.
Among several options we finally chose a pintle style injector used in early space engineering (and more recently by SpaceX).
Studying expired patents we decided to try and revive the vintage hardware using modern software tools. Retracing the basic sketch we convert it to 3D, brake up the components and re-assemble virtually.
Now we can watch the mechanism from all sides and angles, modify to our needs, animate moving parts and get a feel for how the system works. Since we use integrated CAD/CAM we can machine or 3D print the bodies easily, but the beauty of digital is that it saves lots of time and money compared to physical prototyping.
This is prime example of artificial reality merging with real-life, fusing future with the past.
The injector pictured in this update is similar to the one used on the Apollo moon landers. When its shape began to rise straight out of the old patent, it sent chills down our spine.
Like reviving extinct animals from DNA scraps.
“Over the course of the next 20 years, more will change around our line of work (designers, engineers, creatives, artists, entrepreneours) than has happened in the last 2000”
Pintle injector design close to that used on the Apollo landers. This particular patent was filed by the Navy/Spencer in 1971, so we are OK. methink.
Converting the sketches to 3D in a design software and braking them up into components allows us to study their placement and movement, and 3D print them if we want to.
