Hi everyone! I did a little bit of aerodynamic testing yesterday. And my test results are confusing. For testing purposes I used very simple craft as shown on this image. Parts in the vehicle: 1 RT-10 "Hammer" Solid Fuel Booster, 4 Basic Fins and 1 Probodobodyne OKTO2 (hidden inside booster with offset tool). I used almost stock version of the game w/o any gameplay tweaking mods. I verified game cache before tests and everything was fine. Results (approximate with margin of error about 3-5%): [TABLE=class: grid, width: 500] [TR] [TD]Delta-v [/TD] [TD]TWR(surf)[/TD] [TD]Drag[/TD] [TD]Altitude (km)[/TD] [TD]Nose part [/TD] [/TR] [TR] [TD]2466\2828[/TD] [TD]6.35[/TD] [TD]1641[/TD] [TD]49[/TD] [TD]No cone [/TD] [/TR] [TR] [TD]2420\2776[/TD] [TD]6.30[/TD] [TD]1879[/TD] [TD]26[/TD] [TD]Aero cone[/TD] [/TR] [TR] [TD]2355\2702[/TD] [TD]6.23[/TD] [TD]1580[/TD] [TD]42.6[/TD] [TD]Adv. aero cone[/TD] [/TR] [TR] [TD]2450\2811[/TD] [TD]6.34[/TD] [TD]1440 [/TD] [TD]69 [/TD] [TD]Small nose cone [/TD] [/TR] [TR] [TD]2195\2581[/TD] [TD]6.02[/TD] [TD]1357 [/TD] [TD]46[/TD] [TD]Tail connector type A [/TD] [/TR] [TR] [TD]2428\2785[/TD] [TD]6.31[/TD] [TD]1634[/TD] [TD]44[/TD] [TD]Shock air intake (open and closed results are the same) [/TD] [/TR] [TR] [TD]2242\2572[/TD] [TD]6.09[/TD] [TD]1488 [/TD] [TD]39[/TD] [TD]Protective shell 1.5m (pointy shape) [/TD] [/TR] [/TABLE] Isn't it strange that rocket had a better perfomance without nose cone? And why small nose cone is so effective?
