  • About the airfoils.. 7.8 years ago

    A symmetric wing produces the least lift and the least drag, a semi-symmetric wing produces medium lift and medium drag, a flat-bottom wing produces high lift and high drag. If you want a lot of lift with small wing area, you use a wing type with more lift. Otherwise you better take the wing type with the lowest drag and increase wing area for more lift. Also all wing types except symmetric gain more lift with more speed, which may become a problem with stability at low and high speeds.
    They are not airfoils by the way, they are wing shapes.

    @Gameboi14 The restrictions of the challenge say that the planes have to stay below 1000 parts. 999 is below 1000, that's why I won't add another part. :)

  • Educational gearbox model 7.6 years ago

    Kind of, but not really. It would be hard to get a gearbox working in SP, especially because the rotators have a limited rotation speed on free spin, making gear ratios obsolete. Also trying to rotate something faster than that limit will rip it off the rotators.

  • C-666 ADV 5.1 years ago

    @Feanor Your build inspired me and also served as a good base for me to build a highspeed train that actually deserves that name and runs pretty smooth. I also added coaches which are a mix between British MK3 coaches and French TGV coaches with nice interior and working doors. The two heads are basically shortened versions of yours with a few changes here and there. Topspeed is 165 MPH and even in medium corners it can go 80 MPH without a problem.
    Because the design is from you I want to ask for permission to upload. :-)

  • Y U ROLL WHEN PITCH??!! 8.2 years ago

    I also encountered this on my MiG-21. It happens when the CoM is on one level with the CoL and too close to it or generally when the CoM is above the CoL. Something similar happens to real aircraft, that's why you either put the CoM lower than CoL (for stable aircrafts like cargo or passenger planes) or above the CoL (on some fighters for increased maneuverability and less stability, but that needs a flight computer to stay controllable). The same goes with placing the CoM infront or behind the CoL. In SimplePlane it's the best to place the CoM atleast slightly below and infront of the CoL, as we don't have an advanced flight computer to make anything else stable and also the AI can't handle it. :)

    @IamSage Well I'm not really playing this anymore so yeah go ahead, just make sure it's actually an improvement and not a different color scheme or something :D
    According to a previous comment an update made the custom XML settings I did on the prop not work properly anymore I suppose, so that's something that could be fixed.

    The game now also has glass and official instruments and all that fancy stuff.

    @SpencerTreePuncher Yeah it took several days if not weeks to get the dimensions of every part right. I repeatedly drove my truck next to the convoy and looked at any differences and made adjustments until it looked identical.

  • MP May 17th 4.8 years ago

    @BlobfishMaster Yeah, I've worked a lot on it to make the suspension really smooth and tune the gyroscope in it. It helps especially when doing those long jumps. But for climbing it's best to disable it IMO. Otherwise it tries turning you around as you lose traction on the rearwheels.

    I thought about making a side-by-side like the Can-Am Maverick X3. But it's so time consuming and I have a lot of other games to play. Also I fear the small footprint will make it flip a lot.

  • Piper PA-34-200T Seneca II 5.2 years ago

    @Benny3053 LOL, I actually thought about making it five letters so it's 100% correct, but on the other hand it would make the lettering on one side of the wing much wider than on the other side, and I hate asymmetry. Plus I couldn't imagine anyone here would actually notice such a minor detail! :D

  • Piper PA-34-200T Seneca II 5.2 years ago

    @Viper3000ad Yes, there is a veeery slow roll in flight. During the weeks building it I couldn't find the cause, I guess it's some error. You can counter it with a bit of rudder trim though and it adds a bit of realism, as planes in reality also don't fly 100% perfect and need to be trimmed. However on the ground I never had an issue, except for one time when one of the props magically increased it's power. I corrected it and since then it has always been going straight. You could check if your CoT is offcenter and adjust engine power to be equal if it's the case.

    @Nerfenthusiast Yes, it has zero drag. And also zero weight except for the gyroscope, it needs a bit of weight to work correctly.

  • Scorpion V8 Sandrail Buggy Mobile 5.3 years ago

    @Sm10684 Phones have a lot less performance than PCs and in my opinion it's a lot easier to work on PC than on mobile. I could try to make this less performance-hungry, but it's going to cost looks and functions.

  • HSAV Mod. II-Z2 7.0 years ago

    @Smasher I guess you mean that this one is missing the axles (basically the wheels are unpowered now). I tried putting some on after doing the suspension, but they always broke it. I could probably get it right, but messing with the connections in SP is rarely worth the effort and I never sacrifice function for realism. Atleast it now doesn't always jump around and roll over. :D

    @PcWorld2001 I think you got me wrong. This is a mobile SAM launcher, meaning that it can drive around and is not stationary (= mobile). SAM means Surface-to-Air-Missile.

  • Suggestion - Bomb help 8.0 years ago

    Basically you can really forget about drag and just calculate with altitude, airspeed, angle of attack and gravitation. I've read that's also how real attack aircrafts calculate the impact point.

    First you calculate the current vertical velocity (Vy) by multiplying airspeed with the sine of the current angle of attack and multiply the outcome by (-1), if AoA is below 0°, as the outcome would otherwise be negative when flying downwards (below 0° AoA) and we want flying downwards to result in a positive value, just like flying upwards. Flying level at 0° AoA results in 0 vertical velocity at all airspeeds.

    As an example I'll take 450 m/s (~1006 MPH) airspeed at -30° AoA, which results in 225 m/s vertical velocity.

    Now we also need the height and vertical acceleration to calculate the time the projectile needs to hit the ground. In the first calculation we can only use the actual altitude of the aircraft, in further calculation we can use the height deviation between the aircraft and the ground height on the previous impact point for better accuracy (if the game engine allows reading out the ground height at any point of the map). Vertical acceleration is always 9.81 m/s².
    Based on the angle of attack we need to use the right formula.

    For 0° AoA it's just the square root of 2 x height divided by vertical acceleration.

    This is for negative AoA

    This is for positive AoA

    In the example that would be ~5 seconds at 1000 m altitude.

    With the time we can estimate the impact point distance after calculating the horizontal velocity (Vx) of the aircraft by just multiplying the airspeed by the cosine of the angle of attack. At 450 m/s and -30° AoA that is 389.7 m/s horizontal velocity.

    In 5 seconds the projectile would travel 1948.5 m, so the impact point is 1000 m below us and 1948.5 m ahead of us. You could now just put a marker on the ground there, but I would rather like a pipper on the HUD, so we also need the angle between the line from the aircraft to impact point and the direction the aircraft is facing to. The angle between height and distance of 90° gives us a right angled triangle together with the line between aircraft and impact point. For that we first have to know the angle of the line between aircraft and impact point compared to a straight l
