Design Phase, Early Winter 1915
ZhS-8A "Teufel" (20.18 L D75/15) | Roheshmiede-Dehnert "Teufel" | Project Teufel 201815 | Rohesde Teufel 20LD75.R4+2

Following the work on Dehnert 9, resulting in the penultimate Blitz 230, the AvD Motor Company has chosen to develop a new engine utilizing a more efficient thermodynamic process for the combustion cycle, wherein two opposed pistons operate under different work cycles. Due to the innovative nature of this engine, they have chosen to enter collaboration with an industrial giant known for their unique and precise work in the heavy machine industry, Roheshmiede Schwerindustrie, so as to bring a revolutionary engine design into the hands of the Schwarzes Holz Kaiserliche Luftjäger - with the goal of giving out enough power to change the way work is done around aircraft within it and in the empire as a whole. 

After several weeks of brainstorming with his engineers would not bear any fruit, Andreas found himself awake at night, trying to envision in what way he could lead the motor industry forwards. Having worked with motorcycle engines before, he pondered two-stroke radial engines. He required more power from his engines, but was reluctant to convert his Dehnert series to two-stroke variants to avoid their poor filling ratio, fuel inefficiency and lack of effective lubrication generally associated with them. Then again, cranking the RPM of his present radial engines would almost equally shorten their lifespan and introduce issues with air management, while raising the chance of engine knocking… Then it hit him. He could combine the two in a configuration he had seen before in the Gobron-Brillié series of cars from 1900 - an opposed piston engine, but with a continuous burn cycle, working within a single combustion cylinder. That same morning, he raced to his workshop to begin work on a prototype.

The design was not only able to work, but had, in the test case, exibited some very promising effects. As he put it: “This engine configuration proved advantageous in more ways than I could even dream of”. The pistons made it possible to do away with the heavy cylinder heads of conventional engines, thus lightening the entire assembly. It’s thermal efficiency was closer to steam engines - more than twice that of the best internal combustion engines on the market at the time, meaning more power could be transfered directly into useful work, and heat management was easier. This made the engine more reliable and powerful in one - approaching twice the power-to-displacement, than even their testbed, a heavily modified Blitz 230 - a staggering number of 31.22 horsepowers per liter of fuel expended was extrapolated from the one cylinder test bed. Indeed, the prolonged stroke expansion which resulted from this continuous burn could be taken as a reason alongside the lack of a cylinder head, but what really touched Andreas as an engineer were two possibilities which the engine had demonstrated. It allowed the user to modify the compression ratio on the fly, while the engine was still in operation, enabling the pilot to put the engine into a low-stress state if it is damaged, and a higher performance state for military needs, acting as a kind of ‘military overdrive’ for short periods of time, and the smooth, responsive control of the throttle. As the burn was continuous, throttle response manifested directly into power output practically the moment an order was issued. The test bed, however, used a rather complex power transfer system from the ‘outer’, two-stroke pistons, raising the complexity of manufacture and making the machine heavier than what it would optimally allow. To fix this, Stefan had proposed they sign a contract with a heavy industry company for the joint development of the engine, and put the matter of power transfer from the outer pistons into their hands, as well as potential changes to the cooling system, should they come up with a lighter method by any chance.

In the end, the engine was turned inside out, putting the unstable 4 stroke cylinders on the outside to allow for a skipless firing cycle and an arbitrary number of pistons. Complicated gear assemblies previously wider than the engine were shrunk down to only slightly larger than a standard radial crankwheel by using a set of smaller planetary gears to time and draw power from the outer pistons through thin armatures pulling the end of the outer pistons inwards. A set of rails on the rear of the pistons stabilize the armatures, preventing any twisting or bending inside the cylinder. Reduced waste space tightened the center of the engine, allowing better cylinder dimensions.

After several blueprint reworks, endless bickering over the design’s name, the number of cylinders, the stroke and bore, the working speed and various methods of power transfer and airflow, the two had come to an agreement. The design, once drawn out and finalized, called for an 8 cylinder, 20.18 L beast of an engine, with an estimated power output of 630 hp and a diameter somewhat larger than the Dehnert Blitz 230 at 756.5 mm to it’s 547 mm. While the two had their differences, there was no dispute over the fact that the power transmission system developed by Roheshmiede Schwerindustrie proved ideal for the application, and was very much appreciated by the AvD Motor Company, and Andreas personally. Despite the airflow being enough to cool the engine down, Andreas insisted a secondary water cooling unit was installed, with veins going between the cylinders and back in a U curve. This would serve to increase the engine’s reliability with a minimal amount of weight added compared to the primarily water cooled Dehnert 9 series of engines, and would allow for further upgrades to be done later on.

The companies, through collaboration, designed a simple form of direct fuel injection so as to replace the carburattors used on the D9 series and provide potentially better performance in the future. This is done through the usage of a plunger pump, which is actuated by an engine driven lever timed with relation to the engine cycle and which terminates the period of injection by providing a non-return relief valve. This valve is opened by direct contact of the plunger pump towards the end of the delivery stroke, and suddenly interrupts the effective discharge stroke of the plunger. The quantity of fuel delivered is controlled by an adjustable stop arranged to determine the discharge stroke matching the engine cycle, so that it follows the cycle speed curve of the engine and doesn’t hinder throttle performance or cause other complications with fuel feeding. The relief valve thus ensures the time of injection is always at the same point no matter the position on the engine speed curve, load conditions on the engine and sudden changes, such that the injection of fuel at low velocities, resulting in poor combustion, is avoided. This mechanism, thus, allows the engine to be much more compact and makes full use of it’s nature so as to sustain the combustion more reliably.

The one downside of the engine is that as the expansion phase is so lengthened, the air intake and exhaust phases are collapsed into a single stroke, necessitating a source of compressed air to overcome exhaust pressures and properly cycle the oxygen mixture. Fortunately, though, this is an aircraft engine, and wind is a plentiful resource. To capture the wind, two small trumpets are to be extended outside the fuselage of the plane, where funneling will continuously feed the engine’s pressure tank sufficiently pressurized air to operate even at high altitudes where the atmosphere thins. When readying to launch, a small hand pump in the cockpit may be used to pre-fill the air-tank to run the plane up to speeds at which it can replenish itself.

Time: 1 | Progress: 4 | Expense: 6

The engineers assigned to work out the intricate and delicate complex parts of the engine were faced with a revolutionary, if a bit massive of an undertaking. They started work with a nice pace, but it certainty will require much much more than a little paperwork to get done. In fact, making the Adderbolt was easier than making this horrific monstrosity of a machine. Still, despite it all, its not going to cost an arm and a leg like was expected...

ZhS-8A "Teufel" (20.18 L D75/15) | Roheshmiede-Dehnert "Teufel" | Project Teufel 201815 | Rohesde Teufel 20LD75.R4+2| 4/30 progress | 2 PP per die | Rushed 0 times | 2 PP invested



Effectiveness: 6 | Cost: 4 | Bugs: 6

The engine is...well...Honestly, its hard to explain things that have already been explained to the most minute detail. But yes, the engine is exactly as was laid out with all of its specifications... The only real issue, if you could call it that, is that its a bit costly, mostly due to the complexity that would go into its production among other things...But yes, it works, and the man in charge of making these reports who is writing this right now is currently evaluating just what they are doing with their life, describing something that has already been described in the most detailed way imaginable that honestly one would be hard pressed to go even further into detail for without going into detail about things above and beyond simple engineering, for their paycheck...

I'm sure you're all glad to have this report sooner rather than later so...I'll just stop here...

Please don't fire me.



It is now the Revision Phase. You have 2 die remaining to spend on Revisions or Save for the next turn.

The Teufel is now a reality, and just needs to finish. We can invest in it heavily next turn so that it's done either next turn or the turn after that, but we should be capable of using it soon enough. What we need now are some immediate effects to enhance our Adderbolt fleet. To that end I propose a bomb revision and call for someone to work on a parachute revision, since we already have a base for that that just needs to be fixed.

If I decide to write up more revisions, I'll edit them into this post, but for now I'm just going to repost the bomb revision from last turn, since it's pretty much what we need right now in terms of the basics.

Durchfallen Bruchpunkt M-10-50/100/250 (BpM.10-50/100/250)
The goal of this project is to obtain a potent, expendable explosive device for the Luftjager through a revision of the M-08-45's explosive composition ratios, casing characteristics and general modernization so as to allow on-demand bombardment from the skies with specially modified aircraft, such that they may contribute more meaningfully to the situation on the ground with three different sizes available for different mission profiles - a 50, 100 and 250 kg warhead respectively. What's more, it works off the experience gained from the M-09 bomb study to actually finish that program in a decent manner. Work is also to be done so that cheap holders for said bombs are available at insignificant cost for the Adderbolt in the form of clamps actuated with a lever. This is done with the goal of gaining some experience in their construction so that they can be incorporated into future designs more easily, and so there's a solution ready for the Adderbolt at no extra cost, so that the bombs are the only thing the Luftjäger has to worry about when operating Adderbolts in a CAS role.

Revision to Pilot's Gear: Parachute Pack

As the war in the skies continues to escalate, it has become obvious that parachutes like the ones deployed elsewhere in Europe will become a necessity, lest our best pilots face certain death should their plane become inoperable. A waxed cloth dome folded into a backpack set to pop open when a cord is released, the parachute balloons to a giant air-catch when deployed, slowing a fall to a much safer pace.

Efficacy: 1

Apparently, despite knowing what not to do, we still don't know everything that is a 'what not to do' annoyingly enough. Its either that or the Selbstmord-Hülse is such a terrible shell that nothing can be worked out from it...or our engineers set on the project need a pay cut and a demotion if not a request to let the door hit them as they leave. Regardless, one engineer actually managed to produce something of worth out of all of this and made the Durchfallen Bruchpunkt M-10-50, which like the Selbstmord-Hülse, is volatile and likely to explode if handled poorly, but has no propellant inside it, and has a thinner shell to allow more explosive to be put into it along with basic fins... Of course, its not exactly the best, being as likely to explode as he old shell its based on, but at least we can call it with confidence a bomb, if one that is as dangerous to ourselves as it is the enemy... We weren't able to spend much time at a proper clamp, so, we just made it come with a simple wooden box with a trap door to drop it. The pilot shouldn't do any harsh maneuvers before they drop the bomb though, and best not let that box get shot either...It should be noted it also comes with the Bombenschein Bodenkornvisier M-01, though pilots are advised to ease into the dive and not try to do it too fast, just in case...

Revision to Pilot's Gear: Parachute Pack

As the war in the skies continues to escalate, it has become obvious that parachutes like the ones deployed elsewhere in Europe will become a necessity, lest our best pilots face certain death should their plane become inoperable. A waxed cloth dome folded into a backpack set to pop open when a cord is released, the parachute balloons to a giant air-catch when deployed, slowing a fall to a much safer pace.
Efficacy: 6

The Parachute Pack, commonly refereed to simply as the Fallschirm is a large back back of sorts that takes up the space of the pilots seat's back rest and weighs a bit, however with the testing we have done, it was found that it will always save a pilots life...except if the chute ends up getting tangled with their aircraft or something else happens to ruin it, like it being shot at. Regardless, the testing for it made sure that it would work, and usually, in most cases, it will save a pilot or anyone who falls from a great height with it and make sure that they come out of the landing with only a bruise. Though its not perfect and it will give occasionally give the one using it a sprain, or rarely, a broken bone, but it still will save pilots who need to abandon their aircraft. A few engineers joked however, about the Fallschirm being the Kaiserliche Luftjäger's helmet or life jacket considering not everyone will get them, at least at the moment anyway.



It is now the Production & Deployment Phase. You have 16 Production Points remaining.

Quote from: Plan 'Adderscourge'
Fiscal Budget
Scrap:

Purchases:
AvDD.I Adderbolt SBD.I x2 [10 PP]
Fallschirm x2 [2 PP]
Upgrades:
Rote -> Fallschirm
Gold-> Fallschirm

Expenses:

Maintenance:        -4 PP
Left Over:              0 [optimally] PP

Rationalization: So we get two new planes and get a pair of parachutes to protect the Shirohon pilots and Rote, which we'll be sending into the fray. The best layout would probably be 3-3-0 across the theatres. We can let up our defense of the port this turn and focus on maximizing our chances of murderizing them on the other two fronts this turn. Maximum murder on two fronts is better than what we had last turn, and I'm somewhat confident they'll feel as though the other two are more important.
