  1. i have conducted a few tests in the earlier days of 1.0.5 and sadly the pusher design is once again yet farther away from our reach (at least in orbit mode). while on ground mode i was able to produce plate oscillations and sideways force but once in orbit mode the legs cant take the force

    I'm pretty sure it's a bug, otherwise real space programs wouldn't need any engines! It's not just one huge burst of acceleration, it keeps a constant acceleration, as if the decoupler was an engine.

    Wait a second, CONSTANT acceleration? OK I'll test it when I get home.

    If you can please provide more information like logs,save files, craft files and steps for reproduction, also do you run any mods? System data and more, and please could you report it on the bug tracker at bugs.kerbalspaceprogram.com it's be swell

  3. It's not the kraken drive, it's basic Newtonian phyiscs. The octagonal strut is the lightest part in the game and this if you apply a considerable force to it you'll cause it to accelerate to very high speeds, this is not a big but a law of physics, this will work with the new updates (but in 1.0+ it would end up burning in the atmosphere instantly).

  4. For KATEC 

     

    The Pompeii Class submarine. 484 parts 968.3 mT.
    It holds 12 0.625m Timaeus AA/AS missile-torpedoes which are launched vertically with a launch assist system build in the missiles and 4 1.25m Volcan AA/AS missile-torpedoes with explosive warheads for extra tough targets. The sub itself is neutrally buoyant with missile bays closed and a bit (0.1 m/s terminal speed downwards) while full and most of the time while empty and a top speed of 10 m/s

    Action groups:
    1)open the top missile bays for the Timaeus missiles
    2)open the bottom missile bays for the Volcan missiles
    3)activate the engines

  5. would you like a submarine? i have the pompeii class that has 12 0.625 missiles that would look nice coming out of the water and 4 more 1.25 cruise missiles on the underside(also capable of launching from underwater.) for the 0.625 Timaeus missiles is would recommend launching from 25-50 meters below water for maximal dramatic effect with their launch assist system

  8. [quote name='Dr_Turkey']Thank you. Historical Context is important, and the present context, with it's own complex variables and so on, is different from that past context.

    I mean, *gobble!* I hear eating goat this time of year is for cool people! *gobble*[/QUOTE]
    while we dont have the so called "thanks*for killing us all with disease*giving" i think we should get bacon to be the official meat of this holiday also how is it going with the pardon from the president? have you heard back?
  9. [quote name='pellinor']Within the reference frame/SOI of the body you are right. There is a static gravity field and conservation of energy holds, so the gravity assist can only change the direction but not the magnitude of your speed.

    In the reference frame of the parent, things look different. As an example, model the gravity of Mun in the reference Frame of Kerbin. You can do this either with a time-dependent gravity field (the Mun moves), or with a rotating reference frame (coordinates rotate so that the Mnu stays fixed). Both of these models break energy conservation.

    Example: Say a vessel stands still at the height of the Mun orbit (zero kinetic energy). (Say it spends a short time there so that falling towards kerbin is not significant) The Mun approaches, when the SOI catches the vessel, it has a speed "v" relative to Mun which is conserved. It passes Mun's SOI on a hyperbolic trajectory, exiting in a different direction with the same relative speed. Now back in Kerbin's SOI the vessel has a speed (up to 2v), and therefore gained considerable kinetic energy.[/QUOTE]

    you are right but sadly KSP dosnt model the transfer of energy from the assisted body to the craft due to the on rails system, in a completely accurate simulation conservation of energy stays the same as some of the muns energy is transferred to the vessel via the gravitational field

    [quote name='Red Iron Crown']EladDv, it is pointless to talk about gravity assists in a single body perspective, they are not possible.[/QUOTE]
    i know, i have got confused about your post's purpose and have interpreted that you meant to say that the object gained energy relative to the assisted object.
  10. [quote name='Red Iron Crown']Have to disagree here. It doesn't change your speed relative to the body being used for the slingshot, but it does relative to the parent body. After exiting the SoI of the slingshot target, there will be either an increase or decrease of the vessel's semi-major axis compared to before entering that SoI, which means an increase or decrease of the vessel's orbital energy. A gravity assist doesn't just change direction, if it did the SMA would remain the same.[/QUOTE]
    of course. but that depends on the angle of the planet in relation to the original orbital motion, my explanation came from a single body perspective and not talking about the rest of the planetary motion of the vessel, inside the SOI and relative to the used body your energy dosnt change, but in relation to another body yeah it will it's all about frames of reference as if you took the sun compared to kerbin you'd see the force affecting the trajectory and kerbin's one will change too, there is no energy created from nothing(unlike in kerbal where it IS created from nothing because of the on-rails system)
    [FONT=Verdana][quote name='Tatonf']You can't change your orbit without changing the kinetic energy of the ship, i'm pretty sure of this. What you say is very confusing.[/QUOTE]
    kinetic energy yes, mechanic energy no. at the same distance from a parent body(in a simple single body system like ksp RIC) your kinetic energy wont change since the work of gravity is based upon a delta in distance not the actual distance covered(cant remember english term) also any force applied perpendicular to the velocity vector wont change your kinetic energy since again it's a scalar and has no "direction" see- magnetic force always applies perpendicular to an objects speed and the magnetic field's direction and thus can never accelerate a projectile at any of those directions[/FONT]
  11. [quote name='Red Iron Crown']There is a net energy change in the vessel after entering and exiting a body's SoI.[/QUOTE]
    since energy is a scalar and gravity can only transfer energy from kinetic to potential energy and in the reverse when you get out of an SOI in KSP (which is a sphere and since that the potential energy is the same) gravity assists DON'T change your energy at all BUT you momentum does change since it is a vector it's direction is changed by the constant force towards the planet that is perpendicular to the vessel's velocity, still since the energy dosnt change your speed dosnt too. The perceived net energy gain is from the energy you'd need to expend in order to change your vector into the one you get at the end of assist (i am not a professional physicist but still a uni student in physics)
