Wasn't Larry Bell an amazing influence? His insite to our rotorcraft needs
was almost clairvoyant.

Repeated the previous balance runs with helicopter setting on vibration pads
with 3/4" plywood tops. Results: Balancing @ 300 main rotor rpm got
balance down to 0.04ips. The best I've ever seen on a Safari main rotor.
Tail rotor, @1600rpm, is always a problem when running on concrete, was
balanced down to 0.1ips.

Good luck on that one, Sanjay. You should take a look at the
rotorheads forum under pprune.org where there's been a bit of
discussion on this very subject.

I'm not a fan of GAO, couple of reasons. My cousin, now deceased was
head engineer on Glomar Challenger. If you remember when we tried to
get the Russian sub up off the ocean floor, using the Glomar Explorer,
they looked almost identical. He got the Legion of Merit somehow.
Anyway, the Challenger was a National Science Foundation project to do

After 27 years with engineering in support of DoD, and a short course in
"Weapons Systems Acqusition Managment" (WSAM) I became convinced that the
process is more important than the product. The WSAM spent very little time
with the project requirements and all of the time with the management
process. Apparently the belief is that you only need a requirements

Interesting balance job. New Safari and initial balance run. Blades rough
tracked at 300 rpm and a balance run made skids on concrete. Added some
washers using the "Add Opposite" rule but not much change and phase angle
stayed pretty much the same. For an interest, put the helicopter up on
rubber to cancel out any reflected vibrations. What do you think? The same

Stu,
The HTS (High Tip Speed) assembly has a gearbox with a circular boss as
part of the casting. This boss fit into the tail boom and was secured
with 10-32 capscrews that went through the tail boom radially. The
blades were quite small compared to the LTS hardware. The army
complained about a lack of tail rotor authority when using the 269A
