PRESIDENTS MESSAGE JUNE 2021

Fellow Chapter 1111 members,At long last we can break the CoVid imposed restrictions and announce our first official chapter meeting at the newly remodeled FBO on July 8 at 5:30 pm.Weather permitting we plan to set up tables and chairs outside, and a cookout is in the works.
This will be a startup meeting where we will poll the members present for ideas and requests for future meeting topics and goals.We will also begin our fiscal year for membership dues and new member enrollment,so bring your checkbooks or bitcoins 😉 As outlined earlier this year, prorated dues will be $19 for this year through Dec. 31.Cascade Air, our host FBO, will be announcing their open house/fly-in on their website soon. It is tentatively scheduled for early August, so stay tuned

Should be pretty big doings, several large helicopters and visiting aircraft are scheduled.They will be needing some volunteer help with logistics on the ground, so there will be an opportunity for us as a chapter to assist and give back a little in appreciation.In addition we will have a presence to raise our profile and make ourselves known.Possibly a table with some interesting displays, projects? Suggestions welcome!It will be great seeing old faces (Lord knows I’ve got one!) and meeting and introducing new members to the group–hope to see you there! Garnet

OUR CHAPTER IS LOOKING FOR AN EVENT COORDINATOR AND
PILOTS TO QUALIFY TO FLY YOUNG EAGLES THIS SUMMER PILOTS TO QUALIFY TO FLY YOUNG EAGLES THIS SUMMER

It’s been a while since we provided Young Eagles rides at our home airport. The last time was 2013 and the Daily News reporter, Cathy Zimmerman covered it well.

THE PATH TO BEING A QUALIFIED PILOT

Our list of qualified pilots has dwindled over the past seven years. Here is the link to EAA national on how to become a Young Eagles Qualified Pilot. This site covers everything necessary to hold a Young Eagles Event. That includes an event coordinator which is mandatory.

QUICK SUMMARY

Personal requirements include:

Membership in EAA national

Membership in Chapter 1111

Current in the aircraft to be used

Current Medical

Current flight review

Background check

Aircraft requirements include;

Current annual condition inspection and safe for flight

All FAA required paperwork in the aircraft

Liability insurance (explained in the EAA link)

If Experimental, must be in phase 2

If I forgot anything, the EAA web site requirements still apply.

WHO WILL VOLUNTEER TO BE THE EVENT COORDINATOR? THAT IS THE FIRST STEP!

EAA CHAPTER 1111 TECH COUNSELOR REPORT JULY 2021
By Jerry Sorrell

AIRFOILS: WHAT IS INTENDED ISN’T ALWAYS WHAT HAPPENS

Here is a beautifully restored Cessna 195 reflecting the sunlight across the wingspan. There is something undesirable happening to the airfoil while in flight. It looks like there are dents in the upper leading edge of the wing.

The designers didn’t want this, but to keep an airplane light, the thickness of the metal skin has only to meet strength for the design load.

These imperfections might have some impact on how the wing stalls, but likely not enough to worry about.

Some planes with cantilever wings like this Cessna, or RV or Cherokee, may show skin deflection when put into a 60 degree bank (2 G), as the spar slightly bends with the added load. This is not a dangerous thing in an airworthy aircraft, but it might concern a passenger who sees the wing skins flexing.

If an aircraft is pulled into a high “G” maneuver, the yield point may be reached and the wings may remain “bent upward” slightly. This can happen on strut braced planes also, from the strut outward. Buyers beware: An airplane on the ramp with a rippled or wrinkled top surface my have experienced the yield limit. Pass by this deal.

Based on my observation, if you are looking to build or buy a plane with the an airfoil that remains closest to the designers intent, it may be a composite wing made from a carefully designed mold.

Any plane that uses a laminar airfoil requires much attention to wing stiffness to maintain the airfoil across the ribs.

Below is an example of a wing that uses stiffeners perpendicular to the ribs to help maintain the airfoil across the ribs. That makes for a great deal more riveting but really helps the airfoil remain true to design. This was typical in the WW-2 fighter planes. In most experimentals, it is unusual to find stiffeners.

Be careful with paint schemes and thickness across airfoils. Paint trim from the spar ahead and that is perpendicular to the direction of flight can ruin airfoil performance if laminar flow is disrupted by the film thickness of the paint.
