Hi Alansam: check http://www.hobartgpu.com/Hobart%20PDF%20files/GPU%20400.600%20309%20AGE.pdf We have on our facility floor some GPU 400 series units. These type of carts may be plugged onto electrical net of hangars or general standard aviation facilities. You avoid issues about batteries and...

Peter: Sometimes is quite useful to segregate (isolate) the sample or population by ranges (same or similar failure rates) or by types inside de configuration of the aircraft, for example by their ATA 100 codification if it is commercial or by WUC(work unit code) for military. Remember that...

Gerrigroot I'd try Roskam series. It contains a lot of drag estimations for shapes when you are in the design step. regards, FranAle

Thanks Andries: I'm aware about the info you provided. In this case, cracks are located in the aft spar of the vertical fin and they show a typical fatigue pattern. I think that a restore the original strenght process is the most affordable approach to this problem. Off course SRM and standard...

Thanks Kenat: By the way, you are right about BAe System, unfortunately knocking that door have not given the results I expect. The operator is requesting the support but the documentation they have about the repair, adresses to that dwg. I also checked the Civil Aviation Safety Authority...

Hi to all: I'm working on a repair in old jet acft, the BAC Strikmaster MK 89 international version. After som research, SRM calls a drawing no longer available. Does anybody know the nomenclature DWG K-167-03-299? and if you have any clue how to step forward in order to retrieve more...

Check the Roskam'series books, they have good plots and data for propellers. I hope this works for you. FranAle

Thanks IRstuff for your quick answer. now I have some homework to do. It was exactly what I have been looking for. Very helpful. Thanks again. FranAle

I'm dealing with a 20000 pounds acft, single jet engine. I intended to set a complete test for a new drag chute for this acft. Does anybody know a MIL spec, NASA or FAA documents, etc about test procedures on drag chutes? Any clue will be appreciated.

Hi, guys Some devices to prevent surge is to allow the air flow go downstream trought the compressor. This systems are known like bleed air valves or air bleed port. They light the pressure in order to gain air momentum of the air mass flow downstream. Fran Ale

Groveri: Also try AFGROW, USAF reference data for fracture and fatigue analysis. Email me if you need this package. Good luck. Fran Ale

IMAC09: I´ve been working in a100 and be200 for a while. I recommend you, make a isolation check where the ground bonds are. Check the AC43-13B Electrical Systems provided by FAA. You will be surprised what you find.Good luck FranAle

Hi, I suggest you check "landing gear for light aircraft" written by Pazmany. It solve your doubts and give many clues about design and solutions. Francis

I have some experience in TPE331 gas turbine engine.Coking is feature present in some fuels, but you should check the materials´s bearing aft the turbine stage, some are ceramics, it means you should examine the oil quality and of course check the inspection intervals. FranAle

FastMouse I took the pregrade course taught by mister Raymer, and was great, mainly due to very simple Raymer´s approach. It was clear and easy to follow, but I found it a little bit slow, specialy regarding to graphs and data already displayed on the book and by himself. To clarify you, I...
