EAAer Sets 11 New World Records In LW5 AutoGyro
World Record-setting EAAer Andy Keech and the Little Wing LW5 Woodstock.
March 9, 2006 — Andy Keech, EAA 169840, recently set 11 new world autogyro records flying a Little Wing LW5, the fifth in a series of Ron Herron designs. The aircraft, affectionately named "Woodstock," set four autogyro class records and seven autogyro heavy (over 1,102 lbs.) sub-class records.
Earlier this year, Keech sought to test Woodstock in the heavy sub-class where there were only 2 records registered, straight-line distance - 381 miles; and altitude - 10,880 feet. Herron made a number of refinements to LW5, including the addition of two auxiliary long-range tanks; 52 gallons of fuel and heavy cruising blades. Woodstock's take-off weight (1,132lbs) was twice her normal empty weight.
Keech made a series of flights February 9-14 from North Little Rock municipal airport. On February 16, the National Aeronautics Association (NAA), official record certifier, assessed data from the flight recorder, and preliminary results show the following autogyro heavy (over 1,102 lbs.) E3b sub-class world records:
- Distance over a closed course without landing: 667 miles
- Speed over a 500 km closed course: 104.3 mph, exceeding previous mark (83.3 mph) by 25 percent
- Speed over a 1,000 km closed course: 108 mph, exceeding previous mark (81.3 mph) by 33 percent
- Time-to-climb to 3,000 meters: 38 minutes 41 seconds
- Speed over a 100 km closed course: 104 kmh
- Altitude: 14,466 feet, exceeding previous mark (10,880 feet) by 33 percent
- Straight-line distance without landing: 673 miles, exceeding previous mark, (380.5 miles) by 77 percent
Previous records set in the light (1,102 pounds) include:
- Speed over a 500 km closed circuit without payload: 75.4 kts.
- Altitude: 26,408 ft
- Time to Climb to 6,000 m: 24minutes, 28 seconds
- Distance without Landing: 617 miles
Keech is marketing his performance data to potential manufacturers with potential military, law-enforcement, unmanned vehicle, or recreational aircraft applications. "Woodstock is a remarkable all-around performer," Keech says. "But perhaps best of all, it's the safest and least costly rotorcraft in the skies."
Between October 2003 and March 2005, Keech set seven transcontinental speed records in LW5 and also world records: All were set in the light sub-class category (below 1102 lbs.)
