Sorry to hear that my friend, it takes time, so you should take some time just for yourself, but remember the good times and keep those close when you feel the pain....
All the best

Good luck, hope your project goes w...

Re: Engineering Senior Design Project 2011
One of our constraints with this design is that we specified a 25 pound thrust engine or better in our proposal to the school. I should have mentioned that earlier. We're planning on having an engine built by Christmas, and the next semester will consist of running and instrumenting the engine. As ...

Re: Engineering Senior Design Project 2011
The pictures show distortion in a section of a nose cone made by the metal spinning process, the uneven metal thickness results in the distinct bands of distortion you can see, it has nothing to do with the materiel or grade used, the heat from combustion causes the rippling effect as the different ...

Re: Engineering Senior Design Project 2011
Hi, For an engine pick a smaller engine that has more forum posts, that way you will tap in to more experience, very few people bother with big Lockwoods now as the bend is to expensive or hard to come by, they also have a tendency to "suck flat" the exhaust cone when built from carbon steel (it sof...

Re: Pulse jet rocket, first flight (ever?)
Hi Axel Do me a really big favor on your next test flight, could you arrange a good quality microphone and recording set up so that not only the take off is heard but more importantly the actual flight as it progresses up in height and speed, the Doppler rip as it gets going should be really some th...
