  1. http://tass.com/defense/1022432 After an awful lot of delays and redesigns, the second Lada sub, Kronshtadt, has been launched.

    The amplifiers are the bit that benefits from transistors, as opposed to vaccum tubes. What the wiring inside each amp block looks like I'm not sure, I'm not very well aware of how exactly the internals of amplifiers work. I have a few friends who are electrical engineers, I'll ask one. Edit: wiki has a pretty good rundown on the internals. https://en.wikipedia.org/wiki/Operational_amplifier

    Thanks to the miracle of asset reuse, the Red Fox is more detailed than it has any right to be. The gun is a 35mm autocannon, and the cupola and optics (and hatches) stolen from the Norman. The render may not get significantly more complex than the current state, as I lack the time. Regarding the missile, a few notes which popped up: >The intent is to have an MCLOS missile broadly analogous to the AT-5 Spandrel (Though with a larger missile body), easily upgradeable to SACLOS when the tech arrives without loss of capability relative to a purpose-built SACLOS like the AT-5. >The missile is lightly spun to maintain direction throughout flight without requiring constant operator input >I'm also intending for an MLU to replace the rocket motors and warheads >There's space in the nose for a precursor, and the warhead sits a bit further back than is good for it with existing HEAT tech, because a 160mm HEAT warhead even at standoff greater than optimal will kill things pretty dead, and later warheads will benefit from the standoff. Regarding the concept- light tanks are not intended to go toe-to-toe with MBTs or heavy tanks. The 35mm allows the destruction of anything short of a medium tank from the front, and mediums/MBTs at close range from the sides and rear. The missiles are intended to allow self defense and ambush capability against the heaviest vehicles the enemy can field, as well as the destruction of fortifications and strong points, in the absence of heavy enemy armor.

    Might actually be the way to go, if I decode to have my servos air-powered like they are on the TOW. The TOW is however bang-bang, which doesn't work well with human control. We'll see.

    Yes. humans are not good at correcting non-zero side accelerations. Also the PID control is fully realizable with solid-state electronics, which are now available. No need for steampunk.

    PID per Ziegler-Nichols from operator command to servo command, servos on open loop. Where, of course, the full deflection of the operator's joystick would translate to full deflection of control surfaces at launch, decreasing with flight time to allow better accuracy. Space in the turret has been cleared for the SACLOS conscan device, when such a thing will be ready. Also, there's a damned good reason I'm not going with TVC.

    The tail is fixed, and the canards are monobloc control surfaces. The lines on the fins are just a result of how I defined them.

    SS.11 was indeed an inspiration. And it even has a SACLOS upgrade (Harpon) and a few other details I intend to borrow. But it too suffered from the major flaw in the control layout of first-gen ATGMs, which is why I haven't copied its aerodynamics. Also friendly reminder that Azon, Fritz-X, Razon, and other WW2 guided bombs were also MCLOS. As previously stated, I will be exhaustively justifying the ability to build this system.

    The basic form of the Red Fox is now in. Current plate thicknesses are not indicative, and the tires are just for show.

    Secondary armament for the Red Fox light tank/scout car is in: Yes that is a guided missile and yes I will be exhaustively justifying why I believe it to be feasible with the existing tech. The ATGM is MCLOS and easily converted to SACLOS; space will be reserved in the turret for the guidance equipment. The aerodynamic setup is reminiscent of the AT-5 Spandrel, and has been chosen to avoid the most common problem of MCLOS ATGMs as built before the war, and will also be exhaustively discussed in the final submission. Exact dimensions are still liable to change.
  11. Plant is far more important, followed by screw. But flow noise isn't insignificant, and evenly-spaced holes can cause easily-recognized tonals.
  12. All those flooding holes... that thing is unlikely to be particularly quiet.

    This design keeps evolving in a familiar direction... I like the reversed 4th swing arm, very nice detail.

    Really looking familiar... It's like there's an optimum design we're all converging towards. Who'da thunk?
