What happens if a sailplane has no horiz stabilizer or elevator?

Mark,

I've been hitting the books lately. I've just read Aerodynamics for
Naval Aviators (ASA). An excellent treatment of aerodynamics for the
aviator without the oversimplification one typcially sees in most
"learn to fly" books.

It has sections on static and dynamic stability that will help give
you a better grounding for exploring the questions you've asked. And
frankly, it's not bad reading. I was very surprised. Not nearly as
dessicated as I feared. A good addition to any pilot's personal
library.

BTW, it's easy to do the math to figure out what kind of loads you'll
need to produce on the tail to maintain pitch control. Use your weight
and balance calculations to exptrapolate approximations of the moment
arm between cg and center of lift, then match torques with the tail's
moment arm. Repeat this process for a load factor of two or three
(steep turns) and you'll find that you'll need to move a lot of mass
quickly and quite a distance to stay in trim. Just not very practical.
But interesting thoughts.

An excellent book. The only place I found the equation for
the relationship between weight and stall speed. Good
stuff about the different effects of different types of
flaps. Too bad it's buried in the "abyss" (my garage)
due to new space needs (bassinet, changing table, laundry basket,
mom's cozy chair...)



New pilots aren't hard to train, but they sure take a long
time to GROW!

Whoops, a case of typing faster than I was thinking... Ignore the
second half of the last paragraph... it's a misplaced fragment from
another train of thought.
