Hopefully, and from the postings I have read by Phil and Tim about CORE, we may be seeing a new engine for FS11. No one has said anything yet about specifics in their blogs but from what I have read CORE is coming in v1 whichis the current CORE, v2  and v3. As soon as Aces releases Trains2 and then switches from Trains2 to FS11 Phil said he would start to blog/report on FS11 and whats happening. Given technology changes and the shifts at Aces I think we may be in for some fun in the next round of MSFS.

We will just have to wait and see what Phil comes up with next year, or the year after. Hes been keeping things up to date in his blog so I am sure he will let us know as soon as he can about what they have up their sleeve for FSXI


I will take a peek at the reverser too. Panels I dont know but that part I may be able to do something with. If anything I may be able to get the reverser to work by throttle and sound FX even if I can not get the physics result

OK

Mystery solved

I should have just logged int the boeing system to begin with. I still have some access but not as much as I would like sometimes.. LOL

Here is the deal... the SP-5B was going to be redesigned and fitted with a turbofan jet engine.. it never made it past prototype

There were 2 companys bidding on the engine... GE and P&W. Both were placed into the design for testing

http://www.geae.com/engines/military/j85/index.html

So the person who posted that info is either getting old and did not remember correctly or they were part of the prototype testing program, one of the two

(Model 313) P5M-3 - Prototype 4 engined variant, later with
                                     jet engine and BLC system as the P7M-1.
                                     Mock-up only built in 1956.

The engines that went into the model we are working with were upgraded to 3750HP each too so the reduction in prop and increase in HP will probably balance out. The  turbo-compound system increased the HP a few

R-3350-32WA 3,750 hp  turbo-compound 185.66cid

this is one of those "odd-ball" situations where the engine has turbo properties but is not a tuboprop engine. The TP came about later and replaced these designs


So I will import the new numbers I found into the config and see what happens

And.. we're already working under the constraints of the MSFS engine, in that we're fudging turbo-charging, for what was actually super-charging. It's no biggie so long as the max/min MP numbers are accurate, as well as the critical altitude (that's hugely important)..

Edit: And.... the engines are located some 5 feet above the reference line; the float-points are some 10 feet below it. The prop would have to have a cfg diameter of 30+ feet (15' radius) for it to affect water ops. That probelm was an FS9 airfile hangover.

Well the engines in the P5M aircraft that we had were piston type. I was a aircraft electrician, but as I remember they were Pratt and Whitney 3300 or 3350

This pic may help.



Bob

I am waiting for textures from Anthony so i am taking advantage of the time


Fixed:


1.
Fuel pressure... increased in air file, now correct in panel


2.
Minor specs changed for engine and prop

.. made a difference in a few areas, stall was one of them.. and Brett, I read up on these things, they were designed to have a nearly "stall and drop" landing and in fact that maneuver was done all the time in them, even the larger ones   LOL!! So that behavior is normal but now it does stall a bit more efficiently now. I did not make any major changes.

3.
VC light "on" with landing light "on" is still a no-go. I cant seem to figure that one out at all. I am beginning to think its some kind of FSX panel issue

4.
Made some changes in the stress area.. was a bit too high originally which allowed the aircraft to tumble through the air and smack into the water without stopping.. unrealistic.


5.
We all know reverse is not possible w/o being a turboprop so I dropped that idea. They did have this function in the later models according to what I read.




Brett.. you said you made changes to the gear system so she could roll.. can you post those please?

I will send everyone the changes I made in the config and air file later today

Ahhh, OK

I was able to taxi it out of the water and it worked fine





UPDATE ON THE VC lights...  I am able to get the VC lights to stay on if I turn on the overhead panel lights and cycle the landing lights so I think there is something wrong in the panel

It seems to me there is some type of DPDP relay problem in the code. If I cycle the landing lights I must cycle the DOME light switch and then they stay on



Too bad the landing "beam" is so darn bright.. it would be nice if Aces allows single A/c assignment of bitmap for that and allow adjustment of scale in FS11

Update sent via email

Make sure to save what you have and then just let it overwrite


updated air file with fuel pressure and a few other minor changes


updated aircraft.cfg with added weight stations, updated engine data, changes in prop engineering and minor changes to flight tuning


updated sound files.. fixed 'skip' in audio track and also enhanced the low freq


Updated FX and associated sound files

Jim is going to be away for a few days so I think it may be time to let our resident PM-5 crew member test what we have.

Bob.. I will package it up and send it to you with instructions for overwrite of the original and use. Its not finished panel and paint wise but I think its time to let you loose with it and get feedback from you on what we have so far.

It will probably be later today because I need to start a "readme" for it and its installation anyway and now is a good time to start making  that too


I understand Jim sent you something about a possible 'reverse' ability Brett... let me know if that will work or not. If it means switching to turboprop I know that won't work.

The supercharger could be addressed by using the EMERGENCY POWER system the sim allows but that would require special gauges be made and tuned for the booster. What I did was make some changes to the prop engineering to simulate a 'wide open throttle' supercharger which seems to have resolved the power issue but it also means the current RPM gauges are a bit off and could use some fine tuning to make them vary in sync with the throttle better.

The original props were 36-38 degree pitch from the info I found on the Wright engines so the changes I made were not that outrageous and were a bit more realistic to the original aircraft.


Also, the station loads now dictate the aircraft behavior in the water and in flight. If the user wishes to have more challenge in water takeoff and flight behavior, a simple addition of 100-500-1000lbs (each) to the following stations will provide that:

station_load.0 = 170,   33.0, -1.3, 3.6    // "Pilot"                Weight (lbs), longitudinal, lateral, vertical positions from datum (feet)
station_load.1 = 170,   33.0,  1.3, 3.6    // "Co-Pilot"  
   
station_load.3 =   350,   30.0,   0.0, -4.6  // "crew and passengers"            
station_load.4  =  350,   25.0,   0.0, -4.6  // "crew or passengers"

station_load.9  =   880,    -6.0,  0.0, -5.6  // "cargo"
station_load.10 =  590,  -18.0,  0.0, -5.6  // "cargo"
station_load.11 =  250,  -24.0,  0.0, -5.6  // "cargo"
station_load.12 =  180,  -32.0,  0.0, -6.6  // "cargo"



I can simulate JATO units with visuals but I can not add a true "rocket" boost from them. If I could add that boost then the weight can be trimmed higher (up into the 20K+ range... just over 30K is max) and allow the realistic takeoff assist. It could be done with the BOOST system that is allowed though although I would need to exaggerate that systems response to make it work right.



the original engine had a 16:7 gear reduction which is another way we could get the boost power out of the system.. it could vary the prop pitch for the JATO assist simulation too which when tuned correctly with the GR would simulate that very well but that would also require a set of custom RPM gauges to take into account the boost/GR/pitch change, which the King Air I think does now.

Just thoughts and right now she is very impressive compared to the original without any such fancy systems.



I will send the package to you later Bob. If I have any problem getting it out today i will let you know
