Scott, I don't want to offence you, please understand me right, just as a joke :-) Your problem is too much knowledge, you probably know that story about scientists, all the people spend their time to demonstrate that the mission is impossible, but one who didn't know about just did it successfully :-) We know the difference between REAL aero engine and auto conversion, of course you are right, it is not correct to compare mileage in the car with flying hours. There are many different thin points, but the main conclusion, they works and works nice, in our small experimental planes of course.
BR, Alex -----Original Message----- From: krnet-boun...@mylist.net [mailto:krnet-boun...@mylist.net] On Behalf Of Scott Cable Sent: Wednesday, January 14, 2004 6:06 AM To: KRnet Subject: Re: KR>Auto engines-vs Aero Engine Manifesto Dave, Not trying to come across with anything likened to hostility... Please read the whole thread on these issues, It goes back for almost a week now.... I've decided, because this issue seems dear to so many out there, to write a Aero Engine vs. Auto Engine Manifesto of sorts, I plan on formatting this document on a part by part comparison of the differences between the 2 types of engines, and how those differences dramatically impact us, the KR builder community. In short, to reply directly to your comments Dave: When you are comparing the automobile engine application to an Aero engine application, you must consider the differences in environments that these engines are: designed for, fabricated in and operate in. Comparing mileage that's allegedly "trouble-free" is of no importance, because: 1. It doesn't have to operate in the same operating conditions. and 2. The impact of the engine failing while in service is without the life threatening, dire circumstances or predicament that an aero engine faces. i.e. If the auto engine fails, the operator coasts to the side of the road. Systems like redundant, independent ignition systems are a minimum safeguard for a powerplant used in this context. Now for the rest of the KRNetters who have been following this over week-long thread on Engines, I know many of you are just chomping at the bit to hit the Reply key. Please resist the temptation to do so, and be patient, as I am woking on this document fairly dilligently. The reason why I have decided to take on this task is in hopes that with my experience and background will benefit this community. I also feel that I am somewhat? qualified to do such a task because: 1.) I served as an US Army Helicopter: a.) Turbine Engine Mechanic b.) Crew Chief c.) Flight Test Mechanic d.) Aircraft Systems Technician 2.) I served as an US Army Fixed Wing: a.) Crew Chief b.) Maintenance Platoon Sergeant 3.) After the Service I was: a.) Heavy Duty Line Mechanic b.) Cylinder Head Machinist c.) Race Engine Builder 4.) After I finished my Degree I worked in: a.) Hydraulics, Rotors and Controls at MDHC b.) Controls Design on the MD520 Notar, MDX - MD900 Explorer at MDHC c.) Aircraft Structural Design on the Swearingen SJ-30, including the engine installation. d.) Aircraft Jet Engine Design, PW4000. I designed a Hollow Titanium First Stage Compressor Blade for the 777 (48,000 thrust engine) e.) Aircraft Structural Design on the F/A-18 C,D, E & F models, Main Landing Gear Pod Redesign Team on the C-17. Horizontal Redesign Team for the C-17. McDonnell Douglas Phantom Works Design Engineer. f.)Powertrain Design engineer for GM Powertrain's High Feature V-6 engine. g.)Senior Project Engineer for 2nd & 3rd Row Seating for the Trailblazer, Envoy and Bravada Program. h.)Lead Structural Design Engineer for Boeing Integrated Defense Systems back in Phantom Works. Considering that I have worked pretty much every conceivable perspective of this topic. I'm probably, maybe just a little qualified to author such a document? If not, is there another individual who would be willing to take on a task of this magnitude? --- David Lininger <kb0...@positech.net> wrote: We drive our cars up and down mountains with single ignition systems and don't think anything about it, but put that same engine in an airplane at the same altitude and we think we need dual ignition. ===== Scott Cable KR-2S # 735 Wright City, MO s2cab...@yahoo.com __________________________________ Do you Yahoo!?
