I am familiar with those publications, and they are not in the same league with the texts you already have. The Army design guides have lots of sepcification info, so you can nail down the criteria to design to, if you have the Army as a customer. In other words, they tell you what the design answer must be - speeds, structural criteria, strengths, etc. They do not really teach you much about how to get that answer.
For someone who flies a light civil helo, those criteria will read like the specs for Klingon battle tank, at once very strange and also very tough!
