DCS P-47D THUNDERBOLT

***P-47 UPDATE***

:"Warbirds
In addition to completing the final touches to the Spitfire (fuel tanks and bombs), our other primary focus has been the P-47D. More so than any other warbird though, this has been the biggest challenge due to the lack of data. Following the war, all wind tunnel and needed flight dynamics data was destroyed. To overcome this, we are using Flow Vision to recreate the needed data. This has proven a long and expensive endeavor. However, to create the detailed flight dynamics that DCS requires, we consider it mandatory.

Thanks for posting this. I'm certainly interested in the aircraft my grandmother helped build in the 1940's.

Could you look at the links? They're really small and if I click on one I'm taken to the website, but no photo.

Thanks.

Thanks.

 

Yes, I find the links to be bad too.

[Phantom88 3,284]

Yes,My Apologies  

[RichieFly 728]

Thanks for the fix.

Nice looking. Eagle Dynamics are a great bunch.

Great to see this.    Dad flew 93 missions in one of these in WW2.

Hell yeah been looking forward to this bird.   The workhorse in WWII.  

Maybe one of these guys can help with the flight dynamics.

***New**Update***

DCS: P-47 Progress Update
One of the most anticipated WWII modules for DCS is the P-47 and we are excited to say it is getting close. We now have a brand new external model and cockpit in final phase of completion and our FM guru Yo-Yo is hard at work on the turbo-compressor unit and remaining FM issues. It shouldn't be much longer before you will get your hands on this wonderful module.

***P-47 News***

DCS: P-47 Turbocharger Development
Our FM designer, Dmitry “Yo-Yo” Moskalenko, shares some insight into the development of the P-47, specifically the turbocharger unit.

The P-47, in my mind, will be one of our most interesting aircraft from an engine handling point of view. We believe that it will be very challenging for users. It is one of the most interesting planes for developers from an engineer's point of view.


Let’s start from the point that this plane has no automatic boost control for manifold pressure, so it’s very easy to have it under or over-boosted during a dogfight. The automatic turbo governor of A-13 type (the most popular type) is far from perfect as the MP rises during climb and requires the pilot’s attention. Besides that, the pilot must watch the turbine speed and reduce boost not to over-speed as well as watch the carb temperature to avoid detonation.

Modelling the turbocharger, on the one hand, was new for us, but on the other hand, it represented an expansion of our existing thermodynamics method of modelling gas turbines and piston engines. So, we just added two existing parts: a turbine and a compressor coupling with a shaft, as we did for a gas turbine engine. The waste duct – a nozzle with a variable area – was used in our gas turbine engines and even in the War Emergency Power system for FW190A8 (waiting for its red button in the cockpit). The standard P&W R2800-5 engine with two-stage single speed geared supercharger receives fresh air not from the ram inlet but from the turbo supercharger – compressed and warmed through the intercooler which lowers its temperature. The exhaust gas flow feeds the turbine for compression.


Our system of equations, based on mass conservation law for airflow through the engine and gas parameters at each station, is now much heavier than with simple supercharger but remains robust. An automatic governor maintains the backpressure controlling the waste duct area. As nobody knows the exact parameters of the turbine and the charger, research was conducted as usual to determine their parameters from the data contained in several available test reports.


After calculations, the turbocharger was tested using the same schedule as for the real flight test profiles. The results are shown in the graphs. The first graph is a result of the “hands-off” test showing the backpressure kept at the same level as was set on the ground to generate 52” of Manifold Pressure and thus engine power increases with altitude gain. The second graph represents the test with MP kept constant manually, similar to the real test.

DCS: P-47D Thunderbolt

Our next warbird for DCS World will be the P-47D Thunderbolt. The Thunderbolt will be our first allied radial-engine warbird for DCS World, and it will fill in fun and interesting role in operations over western Europe and beyond. Combining both air-to-air and air-to-ground mission capability, it will provide a wealth of mission types, heavy armament, excellent protection, and long-range.


The P-47D is far along in development with mostly flight model tuning, adding object details, and creating the mission content. Suit up!


We plan to release a new World War II Europe map to coincide with the release of the P-47D.

• P-47D-30 Progress -  We are nearly ready to unleash the ‘Jug’ on DCS World! We are finalizing the 3D model and cockpit; making improvements to the fuselage, cowling, and air intakes; and working on externals stores like fuel tanks and bombs.

**some news**

 

Development Report #12
P-47D-30 - Polishing of this module continues with work being done on the animations, textures, flight model, and combiner glass sight. A series of interactive training missions are also being created. We are pleased to share some new images of the Jug taken over the Channel Map. She is getting close!
