OOPS, I couldn't find my copy (still in cartons in the garage, after my move
South) so I THOUGHT I remembered a chapter on it. Oh well, sorry about
that.

OK Nick, what chapter is missing from my copy of "Rotary Wing
Aerodynamics"????

Chapter II - IV is on the Winged (compound) Helicopter.

Chapter II - V is on the Tandem (fore & aft rotors) helicopter.

The Tilt-rotor is covered in 45 words and a picture in Chapter I - I.

As a mater of fact, Stepniewski recommends the Intermeshing configuration
for tomorrow's rotorcraft. http://www.UniCopter.com/1093.html

There are many American Helicopter Society technical papers that have
been given at the AHS annual forum over the years, several at a level
which would be right for undergraduate work. Ask your school librarian
for help, these are usually available in a few days.
Also, Stepniewski and Keys "Rotary Wing Aerodynamics" (Dover
publications) has a major section on tilt rotor design aspects.

For some broad performance comparisons between helicopters and tilt
rotors and supporting sites, see my site:
