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.

rotors and supporting sites, see my site:

Hey guys, I am thinking on giving a seminar on Tilt-Rotor Aircrafts as
a part of my Mechanical Engineering Final Year Syllabus. However all
the info i found on the net (read Google) deals with the BA-609 and the
Osprey specifically and not with the concept of Tilt Rotors. Can anyone
help me out? The seminar has to be about 20 pages long.
