In order for such structure to work properly electrically, few things need to be review. 1) Constant compression part (not necessary a Spring) that take/place slacks due to temperature coefficient of expansion in the battery and the Tube itself, WHILE maintaining rated electrical contact

Along the path investigating yaw control induce drag and efficiency at V-tail, I came to realize that single-sided-rudder-fin has benefit from end plate effect that doubles the fundamental AR in the Cdi formula. The doubling is caused by end plate effect by the horizontal stabilizer. For

[RCSE] Re: Why Vtails?

1999-10-20 Thread Chanyiukwong
Without contradicting all the assertion for V-tails, there is one fact. V-tail has lower yaw efficiency. That yaw function results in higher energy dissipation or losses. To understand that, we may consider two efficiencies, E1 and E2. E1, is associated with the induced force 'normal' to the
