Have fun Cookie, but until you teach them to draw force diagrams, you
will have frustrating conversations. I am a practicing aerodyanmicist, but will refrain from speculation on the tow conditions discussed here. But I will suggest to anyone trying to figure out what the required lift is, that they draw out the forces in what is known as a force diagram. Also known as a free body diagram. http://en.wikipedia.org/wiki/Force_diagram In un-accelerated flight, which includes aerotow at a constant speed and climb rate. All the forces, including gravity must add up to zero. |

All the forces, including gravity must add up to zero. yeah.........this has really branched into two discussions........the forces of flight, and why a slow tow is bad. but force diagrams make it really simple to visualise what is going on. But on tow, with down wash and vortexes and stuff it is hard to figure what and where the forces really are. (remember the discussion on "gravity power"?) Cookie |
