Dave,
How can you say that helicopter main rotor blades are not twisted? This is one of the easiest ways to improve the Figure of Merit of a rotor and some degree of linear twist is used on pretty much every main rotor blade in use today. Almost all of the have a linear twist of somewhere...
Before Composites were widely use blades were twisted by creating the spar and physically clamping the hub end of the blade and manually twisting along the span. Most likely you will want to do this in a linear fashion (max twist near hub and minimum twist near tip) in order to improve rotor...
I agree that the landing gear is a less than ideal (if not one of the worst) places to mount the device. Though I did not see the actual oscillation of the boom last summer, from what I understand it was really quite large in amplitude. Small vibrations are ok. I am just looking for any tricks...
ello all,
I have recently been assigned the task of fixing part of an experiment that was conducted last summer and will be repeated this summer. Part of the experiment involves taking air data measurements from a flying helicopter (Bell 206). This was done using an air data boom...
