Apco Keara

apcokeara

Although released during the 2nd half of 2002, the KEARA was Apco's new star for the year. Introduced as Simba's daughter (a character from Disney's story of the Lion King), it is said to be inheriting all Simba's virtues and more: faster, more powerful and better performing.

The leading edge of the Keara features Flexon Nylon Battens which hold the profile shape at speed, and HIT Valves (High-Speed Intake Valves). "HIT Valves" increase the internal pressure of the wing both during accelerated flight and in extreme situations, improving safety and performance. The "HIT Valve", placed above the leading edge openings, opens automatically when the stagnation point moves over the valves, pressurizing the wing. Only a few valves are necessary over the span of the leading edge to pressurize the entire wing at higher speeds.

The HIT is a sequence of meshed valves above the leading edge opening, which are closed during flight on trim speed (average angle of attack), but open once the angle of attack is reduced and speed is increased. Apco claims that this "ensures a rock-solid wing at highest possible speed".
KEARA also introduces a semi rigid leading edge that helps keep the profile definition. Apco calls it FLEXON batten technology, and it reminds us of Gin's Rigi-foil system introduced for the first time with the Boomerang, in 2001, which inspired other manufacturers to work on semi-rigid leading edges (e.g. Windtech's Syncro also features a version on this subject). The Flexon battens support the top and bottom surface leading-edge fabric between the ribs, keeping the profile clean and the intakes open. This feature is supposed to improve the performance of the wing, especially at high speeds, and also improve inflation of the wing both during launch and re-inflation in flight, according to the manufacturer. Apco has also certified a competition version of KEARA with unsheathed thin lines.
Apco Keara: A question of Speed

Apco's leader Anatoly Cohn is not happy. His newborn star for the intermediate-advanced pilot, the Keara, was measured a much lower top speed by the DHV than Apco's promises. The company had claimed that the glider could reach a maximum speed of 59k/h, while the certification organ published a humble 51k/h, which they had to correct later saying that the measures were taken with trims closed. Now, the top speed published by the DHV for all the certified sizes is 54k/h, but Anatoly Cohn has expressed his nuisance in a letter sent to Apco's dealers, stating that "DHV officials explained and admitted that their speed measurements do not reflect true, top speed capacity of the glider and they do not aim to record it as they certify Safety, not Performance". And so he reassures that the model does reach 59k/h: "We stand firmly behind our measurements and support them as true, realistic figures. We conducted many comparative speed runs and are faster than many other DHV 2-3 or DHV 3 gliders for which DHV recorded top speeds of 56km/h, 57km/h or even faster". He encourages pilots to test fly the Keara by themselves and conduct their own comparisons with other paragliders, paying special attention to speed. He seems to be completely sure that the Keara will win most races. Cohn believes that from now on DHV will avoid publishing top speed figures, "as they are not reliable or objective and should not be used in manufacturers marketing hype".
