Altitude is pret' near self-explanatory; whoever's rocket reaches the highest altitude, in a given engine class, they're the winner. Most folks ask how the altitude is ascertained. There are two men set up at tracking stations. The instrument used is no more than a surveyor's theodolite, set up at the end of a known baseline. The tracker sights on the rocket, and takes an elevation and azimuth angle at apogee. Then a complex arithmetic calculation is used to obtain the altitude. If the two trackers agree within 5%, then you've got an official or "closed" track. Yep, that's the FSI kit specially designed for the F7 engine. Swelp me if I can remember what they called it, but it's an awesome flyer! And no, I wasn't any competition to the composite-engined F Altitude boys with this one.. it was fun, though! |
