(Edit on 10-20-21: In the following posts Kv or KV is used to describe brushless EDF motors. It is not kilovolt. The Kv rating is the ratio of the motor's unloaded RPM to the peak voltage on the wires connected to the coils.)
I'm building a rocket using a 70 mm Electric Ducted Fan (EDF). Others have used EDF's but mostly to achieve controlled landings like a Falcon 9. My rocket will recover using a parachute. My objective is close to 2:1 thrust to mass but this will be difficult. The 70 mm EDF is capable of about a 1200 gram thrust at 100% throttle, but I still need to run static tests for thrust and several batteries. Anyway, I'm being careful to manage mass for this project.
Please note, I called the thread EDF Rocketry because I'm interested in what others are doing with EDF's in amateur rockets. Another example of what I'm doing is using a EDF on a lifting body aircraft deployed from an aeroshell on a rocket.
The design and use of EDF's is very interesting and different that using typical rocket motors. I'm even considering using a mix of solid rocket motors and a EDF. My following posts will probably be more images than anything else. Here's the first.
