A nice annimation on youtube from the History Channel.

The possible repetition of approach to target was considered as one of the essential advantages of the underwater- air torpedo bomber over traditional submarines. Especially effective it had to be the action of the flying submarines in the group, since theoretically three such apparatuses created on the way of enemy the impervious barrier by width to nine miles. LPL could penetrate at night the harbor and the ports of enemy, be immersed, and in the daytime conduct observation, direction-finding of secret fairways and with the opportunity attack. In the construction LPL were provided for six autonomous sections, in three of which were placed the aircraft engines AM-34 a with power of 1000 hp each each. They were supplied with the superchargers, which allowed boosting in the takeoff conditions to 1200 hp the fourth section was habitable, calculated for the command of three people. Control of vessel under water was conducted from it. In the fifth section was located storage battery, in the sixth - rowing electromotor by power 10 l,s. Durable housing LPL was cylindrical riveted construction with the diameter of 1,4 m from duralumin with a thickness of 6 mm. besides the durable sections, boat had wet type pilot's light cab, which with the sinking was filled up with water, in this case flying instruments battened down in the special mine.

Skin it is wing and the tail assembly it was intended to carry out made of steel, and floats from duralumin. Etielementy of construction not were calculated for the increased external pressure, since with the sinking they were heated by the sea water, which entered by drift through the scuppers (openings for the drain of water). Fuel- (gasoline) and oil were stored in the special rubber reservoirs, which were being located in the center section. With the sinking that moving and that discharges the mains of the water cooling system of aircraft engines overlapped, which excluded their damage under the effect of pressure of outboard water. The painting and varnishing of its skin was provided for for the protection of housing from the corrosion. Torpedoes were placed under the outer planes of wing on the special holders. The design payload of boat composed 44,5% of the total gross weight of apparatus, which was common for heavy type machines.

The process of sinking included four stages: the sealing down of motor sections, the overlapping of water in the radiators, the transfer of control into the underwater and transfer of crew from the cab into the crew quarters (central control).

For CFS2, FS2002, FS2004


  • Yes, you CAN sink underwater, and surface again, using the wing fold command. VC view moves back and up into the conning tower (central control), where you are looking at the surface through the periscope!
  • Published estimated cruising speed and range are too slow in comparison to other aircraft of the era; project stall speed 55.6 knots, cruising speed 155 knots, max speed 183 knots, range 950 miles.
  • Russian gauges by MoparMike.
  • Bf-100 sound files by Mike Hambly and Gert-jaap van der Bij
  • Multi-LOD
  • 2D and VC
  • DXT3 textures
FS2004


  • Tailored flight dynamics files, initially developed with Jerry Beckwith's Flight Dynamics Workbook.
  • VC Rain
  • All annimations work
FS2002


  • Includes FS2004 model file converted with Ivan Hsu's MDLC for maximum annimations.
  • Tailored flight dynamics files, initially developed with Jerry Beckwith's Flight Dynamics Workbook.
CFS2


  • Tailored flight dynamics files, initially developed with Jerry Beckwith's Flight Dynamics Workbook.
  • To include Thicko's Russian Torpedo load, but need to get his permission first.
  • Breaking parts
  • Reflective shine and FS2004 model conversion by Ivan Hsu's MDLC
  • Although it appears the machine guns were intended to be fired while stationary, they work in the air as well (to give CFS2 pilots a "fighting chance.")
Current Issues


  • The CFS2 version flies at too fast a speed, still trying to figure out how to slow it down.
  • The torpedo is not annimated in CFS2; can't figure why at this time.
Status


  • Exterior mostly finished; need to cut exhaust ports (like gun ports)
  • Need to add throttle levers, and texture many interior parts
  • Few other odd details.

Very interesting! Will be a fun aircraft to use in CFS2 for sure.

On the torpedo tip...the torpedoes are modeled on for the FS2004 version, I would assume. And you are converting the FS2004 version to CFS2 using MDLC. Which means that the torps are still modeled on. What you really need to do is to create a second model without the torpedos, make that into the CFS2 version, then the working torps will be placed via the DP file.

Actually, what I am doing at the present time is:

1. Compile once for the FS2004 model.
2. Compile again, and convert with MDLC for the FS2002 model.
3. Remove the torpedoes, compile and convert yet again for CFS2, with dynamic shine and fix annimation switches on. :isadizzy:

I leave the torpedo mounts in place, and have adjusted thicko's torpedo loads to mount in the correct location. This all works well; except the controls are not annimated in the VC in CFS2.

Once the model is completed, I do need to make a CFS2 version of the model, and rename as many controls as I can to the correct name for use in CFS2; and recompile and convert. That will hopefully result in more VC annimations; though I do need to find a listing of what names are supported by CFS2; some are mentioned in the documentation for MDLC.

You stated that the torpedo is not animated in CFS2. Wat exactly is the torpedo animation that you are trying to achieve?

In CFS2, when you have a properely designed .dp file, you can see the bombs and torpedoes fall away from the plane. A torpedo then moves through the water until it hits something and explodes; bombs of course explode when they hit the ground.

If it is not properely designed, bombs and torpedoes just disappear when you drop them. I was able to make torpedoes work correctly when I was working on the QH-50 remote control helicopter; but I am not holding my mouth correctly or doing something else wrong on the LPL. Thicko's bombs and torpedoes work correctly on his Ilyushin IL4 I downloaded, but not on the LPL, so I am doing something wrong in the .dp file.
 
I think in my original .dp file, I set the number of torpedoes to zero, as per the thread you linked to. I changed it to two, will see tonight if it works.

Peculiar aircraft are so interesting to me. I have to wonder what was going on in these designers heads when they come up with these things. The Germans seemed very open to new and strange designs, possibly out of desperation or maybe they were just allowed to. The asymmetrical craft of Bohm and Voss are also very intriguing. Obviously the Russians were the same. I cannot wait for this little treat!

ETA? :running: no rush!

Re: Torpedo

Are you using the Mk-10?

If not, find it included in VN's Pt boat:

Click to expand...

I am examining the Mk-10 installation on the VN Pt Boat; thanks for pointing it out to me.

I got the torpedoes working over the weekend; but found they could not be launched underwater, and would just blow up when launched on the surface. The VN Pt boat obviously is able to launch torpedoes on the surface, so I am trying to figure out how.

The Mk-10 is an aircraft or model; instead of a weapon. Once again, trying to figure it how it works. The PT boat carries it's torpedoes in tubes; so they are not visible. I am not sure at this time if it models the actual torpedo or not.

(Which lead me to wonder how the real plane would have fired it's torpedoes had it been built. The drawings suggest the same type mount used by other torpedo planes, but would simply dropping them on the water's surface or underwater have worked? Submarines/torpedo boats/destroyers all launched them from tubes; I assume so they will travel straight after launch, and not just drift off to one side or the other.)

Like I said, I still have to build the throttle levers, and texture much of the interior. Would like the CFS2 version to fly slower, but haven't figured out how yet. Need to model the exhaust ports.

I am working on it during my lunch hours and testing in the evenings; but think I may have an initial release ready. I may also off the following paint scheme as well; and someone requested a Cuban scheme as well.

I can share some screen shots shortly.

A sneak preview:

Doing it's thing in Combat Flight Simulator 2 with it's 1930s livery; note Thicko's torpedo is now falling away, as it should.


The 1941 Soviet Air Force livery (looks great on my machine at home, but looks completely dark here at work) in FS2002. The sinking sequence begins with the engines sealed and the craft settling down on it's floats; the crew inside move back and up the ladder into central control.


In the VC, your viewpoint also moves back, up the ladder, and into central control. Here also is a good shot of MoparMike's Soviet four engine gauges; I still have the prop pitch and mixture levers and trim wheels to model.


Once it has settled onto it's floats, it then sinks underwater as the floats fill with water. The whole sequence happens at about the same speed it would have happened in reality; it is greatly speeded up in the History Channel sequence above.


Inside the VC, we are now inside central control, looking through the periscope.


The diving process completed, we now start our "electric motor" (the engines), and begin our exploration of the harbor. It is hard to maintain just 4-5 knots underwater; espcially in a surface chop.


And as per request, here is my initial try at a Cuban air force livery for the sole elderly aircraft sent with a bunch of spares to Castro in the hopes he could put it to use. (In FS2004)


I may end up redoing the exterior texturing as well. Also found the correct angle to cut the exhaust ports, but still need to do so.
