  • Funky Trees! 2.8 years ago

    @linxiaofeng2339 is IAS divided by TAS really the pressure ratio?
    Bernoulli's equation suggests a difference of 1/2rhov^2 between pitot and static pressure, however rho and pressure are not completely linked (as temperature is different at different altitudes).
    Even if the temperature was constant, then it should be p(current)/p(sea level) = (IAS/TAS) squared, not just (IAS/TAS).
    I don't think we have verified whether the ISA (International Standard Atmosphere) model applies to SimplePlanes, which would allow us to deduce the pressure and temperature at different altitudes.
    (I was trying to calculate Mach Number, and as we know the speed of sound changes with air temperature, so I ran into a similar problem)

    Max operational alt.: 85000ft at 720mph
    Max alt:~91000ft at 710mph
    Max cruise speed:720-730mph

  • Air speeder Mk.3 ideas 7.2 years ago

    I have a single engine plane that goes 930mph without modding (just normal engines), and with three Cleaver Missiles attached to the wings. The essence is to make the drag points as low as possible (around 600), which your MK2 does not satisfy. Using a rotated Fuselage Inlet you can attach an engine behind other blocks, which gives much lower drag points.

  • bring back bullet weight XML option! 7.2 years ago

    Yeah that's a must... How fun it is to punch bridges and ships with a single shot...

  • Tough Planes Challenge! 7.2 years ago

    I have a bulletproof plane that can take up loads of bullet damage (I haven't uploaded yet), but missile proof? It can take 1 hit and no more... BTW does anyone know how to get to avalanche airport? I accidentally lost my data...

  • New weapons platform 7.2 years ago

    Yeah just using flares is not enough... turning and accelerating is also necessary @palidinwaraxe55

  • It's time for a BIG plane! 7.3 years ago

    Boeing cockpit, but no idea of which model...

  • How to get to the islands. 7.5 years ago

    I do see the gigantic squid, but what? 'Cthulu??'

  • How to get to the islands. 7.5 years ago

    After you hit Cthulu does it become an island? Does it become an airport? How is it like? I can't manage to get the prompt (Location Discovered)

  • Perpetual Airplane: No fuel 3 7.6 years ago

    Its optimum climb speed and max speed are both 53mph, since the props are long and sleek but not wide.

  • Perpetual Airplane: No fuel 3 7.6 years ago

    It has a better thrust to weight ratio than most others and climbs quite quickly.

  • Piston Perpetual Aircraft 7.6 years ago

    Thanks! There is now an even better version of this plane, check it out! @MrSilverWolf

  • Piston Perpetual Aircraft 7.6 years ago

    I just found out that I should make the tail fin larger for better turns... Please change it yourself... My apologies.

  • Long-25B ballistic missile 7.6 years ago

    太厉害了!

    Good job cosmo

  • Aircraft vtol test test 7.7 years ago

    Great work!
