Hi Raimo, Are you saying that Finnish people understand this legal gibberish?? I have a number of friends in Helsinki and while they usually understand me, I don't believe they would handle BrusX any

....most commercial GA aircraft have two blade props... Actually as can be seen convincingly in a stroll about Sun and Fun today, any new, high performance aircraft , i.e., Cirrus, Cessna, Mooney, La
Actually 2 blades being longer radii get less efficient as the length blade in the transonic or faster regime grows. More blades keeps the tips out of the transonic regime by keeping the radius down.
The Dinner meeting venue was shared by good company. As promised, the prop blade number issue was discussed - for about 20 seconds. -- Ira N224XS Read this topic online here: http://forums.matronics.
Hi Ron, Two notes of caution since your design probably won't be tested for several years to come. 1) Sucking air from a plenum is not as effective at cooling as a ductdirected push of cooling air at
Just like cooling inside the cowl, cooling of the instrument panel can be non-or counter intuitive. In some engine cowls, the air pressure gradients and consequent flow can be stagnant or even flowin
There are different classes of experimental aircraft in the US. Some types are restricted to certain areas or require FAA notification to move. These restrictions do not encumber owner-built experime
Try it stoichiometrically: Air flow must be proportional to fuel flow Use a ratio of 15:1 (just easier that 14.7 reference value) so 1 gallon per hour (6 lbs) is 15*6 = 90 pounds/air per hour Dry air
Hi Bill, Can you tell us how you prepped the firewall for bonding? It needs to be chemically clean and well scuff sanded to provide a good key. -- Ira N224XS Read this topic online here: http://forum
For the case of the trigear, one can only imagine a worse case. It seems unlikely that a trigear can be prevented from digging in at the nose and possibly cracking the canopy. I fly over the Long Isl
Frans, The main gear touching the water will cause pitching moment nose down because the wheels, with no rolling will be retarded by water like hitting a brick wall. This is completely unlike the bal
I think the dbs on the panel module should be male instead of female as you propose. After all, the module is inserted into the fuse!! Actually, I used CPC connectors because they are engineered for
I have three CPCs, left right and center tunnel. I am not sure what you are referring to as "fuse" wires. Do you mean thin wires ala Nuckolls? Why would you put them in a plastic connector when if th
Nylon slowly depolymerizes in sunight leading to embrittlement, and 14 years of service should have slowly accumulated a number of small cracks due to constant flexing loads. Shouldn't these componen
My CPCs are mounted on the forward lateral bottoms of the IM. The center tunnel CPC is mounted forward bottom, above the port side of the tunnel. The "fuse" connectors are short pigtailed from the wa
I don't believe nylon polymer is the wrong material for the application. When new it is probably a lot better in flex than some sort of FRP. Fourteen years just seems a really long time to have any s
Hi Ferg, Actually, it is Rotax's intent that airframe manufacturers measure the reservoir temp, not individual builders. The idea is to be absolutely sure that the engine cooling system never allows
Hi Ferg, The reason Rotax requested that this temp be measured (at least once) per design is that they did not want to engage in the guessing game. Anyway, my coolant temps are essentially equal to m
I believe the F models were indeed certificated, although I was unaware of a 914F. The Diamond Katana aircraft used a certificated 912 starting in about 1994 -- Ira N224XS Read this topic online here
