[49] During the descent, Kittinger experienced temperatures as low as 94F (70C). I think the quickestway PD coulddo it would be to get fourgroups of five test jumpers (20total) w/ FlySightand do one load for each canopy type of various sizes with test jumpers within theweight range alignedin their WL recommendations. Glide Ratio at Full Glide: The St iletto has a slightly flatter glide angle at full glide than the Sabre. Parachute Type: Elliptical 9 Cell Ram Air, Pressurized Stabilizers Max All Up Weight: 450 lb (204 kg) Canopy Area: 360 ft (33.4 m2) Span: 31.7 ft (9.7 m) Aspect Ratio: 2.79 (b2/Sw) Chord Middle: 12 ft (3.7 m) Chord Tips: 9.7 ft (3 m) Deployment Method: Free Fall, Static Line Line strength and Type: Spectra 1000 lb (454 kg) Deployment Altitude FWIW, my belief is that thebiggest factors are first line trims and secondly aspect ratios. "Jumper-In-Tow" involves a static line that does not disconnect, resulting in a jumper being towed behind the aircraft. The m ethods and procedures described in this section are app lied to a model ram - air parachute system . He fitted the aircraft with two small Chrysler engines, resulting in the first prototype P-1 aircraft.[14]. The most common fabric today is nylon. Hmmm. That portion then forms a secondary lobe with the canopy inverted. Parachute Duration - National Association of Rocketry After Adeline Gray made the first jump using a nylon parachute in June 1942, the industry switched to nylon.[39]. Ribbon and ring parachutes have similarities to annular designs. They do tons and tons of test jumps. That is, airplane flight data is always adjusted to be what it would be at sea level, International Standard Atmosphere conditions (29.92"Hg, 15 deg C), that sort of thing. A low stall speed is desired for safe landings. Ribbon parachutes have a ring-shaped canopy, often with a large hole in the centre to release the pressure. Also in 1785, Jean-Pierre Blanchard demonstrated it as a means of safely disembarking from a hot-air balloon. If they don't know, call Flight Service (800-992-7433). Most sport jumpers fly with wing loading between 5 and 7 kg per square meter, but many interested in performance landings exceed this wing loading. Parachute Duration combines the challenge of building a light rocket that can carry a large enough parachute to descend slowly, yet being able to deploy reliably, to achieve a good duration score.
