Thanks for the kind words. I gave away lots of my article secrets in this blog, so I saved the humor for the article.

The purpose of that speed flight was to see how the helicopter reacted to higher speeds, so they didn’t do climb tests. The idea is that the airframe made it through 263, even in a descent, without loss of stability or needing more tail surface (which WAS the case at 181 knots).

Now I can’t wait to read it! And by the way, I think the writing in your blog is concise and cogent. I write about helicopter-related news myself, and I must say that the earlier comment was a little harsh. Typos happen to the best of us. Those are easy to fix. More important is the quality of content, and your posts are well-covered in that department. Keep those AOPA Pilot teases coming :)

The Eurocopter also uses auxiliary wings as well, and a single rotor. Two propellers power it to higher speeds. Sikorsky claims this makes it less like a helicopter, while theirs retains all the characteristics of helicopter flight. They also claim they have more power for the propeller, given that there is no tail rotor, and that the savings in power is 15 percent. The two designs will do battle in the upcoming competition to win the armed aerial scout contract.

In recent years the Piasecki research and development organization devised an experimental helicopter which is a modification of the familiar Black Hawk. Instead of counter-rotating concentric twin main rotors and a pusher prop, the Piasecki design uses a combined antitorque and propulsor system at the rear, a single main rotor, and auxiliary wings. It would be interesting to see both the Sikorsky and Piasecki designs.

So, so many have been posted, replete with typographical and grammatical errors. People seem to be in too much of a rush to get something posted that they fail to take the time to re-read what they’ve written. Especially for those working for professional organizations, it makes you look far less professional. It’s difficult to take you seriously. Thanks.
