Wikipedia:Yaw string
The Wikipedia article on the yaw string is featured on the main page
today in the "Did you know...." section as follows: "Did you know..." ....that the yaw string, a simple tuft of yarn used as a flight instrument by the Wright brothers, is still in use today?" http://en.wikipedia.org/wiki/Yaw_string |

Nice work, ongoing! Doug....
These entries are surely very subtle yet powerful advertising for the challenges of our sport. Too bad we can't track how many people show up at a club saying... "I was browsing this Wikipedia article and thought I'd give it a try!"

More surprisingly to me is the information that...
Yaw strings are also fitted to the Lockheed U-2 high-altitude surveillance aircraft http://www.barryschiff.com/high_flight.htm .... but given how close U2s are to falling out the sky at altitude (the coffin corner), perhaps it isn't too surprising. |

Yaw strings have also been found on USAF fighters. They aid in gunnery training. Jack |

They was also a provisions for a yaw string on the F-4 Phantom.

Nor did they mention the vastly improved yaw string, the MKII "high tech"
yaw string! The MKII is reputed, by generally refutable and unreliable sources, to increase L/D by at least 2 points - - but who's counting. This from the inventor of the "QV quiet vent kit" (which really does decrease noise from the Mecaplex flip-out window vent by a full 10 db as measured in an ASH26E at 60 knots). Contact me directly for more info. I'll have a supply of both with me at the SSA convention. bumper ZZ (reverse all after @) "Dare to be different . . . circle in sink."

Some of us are waiting with abated breath (nothing
fishy here) for the Mark III calibrated model. It is reported to have a transparent sweep screen underneath it so as to measure the precise angle of slip and aid in selecting the amount of rudder input required.

Nyal,
I love a challenge(g). However, including a sweep screen with photo-optical sensor to provide data to a remote digital angle-of-slip indicator, would cause a bodacious increase in the $9 selling price. We could go low tech though. Since the MKII yaw string already comes with transparent turbulator base and a single light colored alignment dot*, it wouldn't be that much trouble to include two additional alignment dots and a template to install them at say, 10 degrees each side of center. *The center alignment dot, affixed to the inside of the canopy surface, is light colored so it doesn't tend to attract the eye, tricking it into thinking it's outside traffic, as would a dark colored dot. As an aside, I've seen several MKII yaw string installations where the pilot chose not to install the included alignment dot as all. So clearly all this is a matter of preference . . . as is the decision to continue using that ugly old tape and yarn!!. -- bumper ZZ (reverse all after @) "Dare to be different . . . circle in sink."

Darn things work even better when you tape both ends down. Just have
to make sure it's on straight first... And they last longer on the inside of the canopy, anyway. 66 |
