The props are like this because they are in the full feather position, as are most turboprops when they are shut down. The engine is started in full feather and then brought through beta to fine/forward pitch. Hope that helps.
@dkervinen its also worth noting that some engines, such as the garret engine, dont have their prop connected to a free turbine so they start while in the beta range
why do the propellers look like that on turboprops? The inner hub area looks like it's sweeping forward and after it gets past the middle, portion, then it tapers outwards like a normal prop. These props are capable of feathering yes? What angle are the propellers at when you start them?
Hi, excellent video, Im from Colombia, and Im a pilot to, and I like much the private aviation, I want to ask you if it has a vacancy for me to be employed at your air team, please help me, tanks....................
actually several turbine biplane already exist, the ag cat crop duster that bear the turbo name with the aerodynamic nose, air inlet at bottom and 2 exhaust nozzle being at the side of the engine, one exhaust nozzle at each side.
The clicking sound you hear are the excitors (which are like super high intensity spark plugs) which is part of the start sequence, all controlled by a computer. Once the turbine is lit it will stop, which is usually the first 10 seconds of spool up. Hope that helps. Cheers.
this airplane is so cool! and whats better that it is at san carlos airport and it very close to where i live and my dad parks his airplane there too ! and its sooo cool to watch it go flying!
re:the steep blade angle ; the propellers on turboprops have variable pitch and to protect the pitch change mechanism from corrosion the blades go to high pitch on shutdown
Actually, the blades are either "feathered "by the pilot on shutdown (as in this video)or you can actually not touch the prop control and the decreasing oil pressure in the prop hub will eventually cause it (the prop) to feather at a much slower rate, even when completely stopped. The only concern about corrosion of the blade tips is not to use reverse below 40 knots as it tends to pickup debris/small rocks...etc. Hope this helps... (Kingair 200 driver)
Because it is an airplane and not a helicopter.... OK, the reason for starting in flat pitch is that it does not develop any thrust, which is safer and keeps FOD from entering the turbine.
What are the advantages of having a turboprop engine over a regular et engine? Also,how does changing the pitch and shape of the propeller blades affect the performance of the aircraft?
Turboprops harness a greater amount of the energy produced by the engine than is possible by using the thrust alone, so you get much greater output per unit of fuel consumed. Passenger jets use turbofans, which are a similar concept (Wiki it.)
Changing the pitch of the propeller is like switching gears in a car. Higher pitch = more AOA = more pull = more drag. You can increase pitch for a stronger pull, and reduce it when you are in a cruise.
Very nice this is the first time I see how this thing sounds close up,and the video is also very clear.Are the props only twisted with turbine enjines?
The propeller blades are in full feather. You'll see this on turboprops as most (like the Turbine Toucan) have reverse pitch. We start the engine in the feather position and then we can go into forward pitch or reverse, if we want to back up the plane:)
That is a very good guess. All turboprops have what they call exciters, which is similar to spark plugs but perhaps a thousand times more energy. As soon as you light it off the exciters stop (about 10 seconds).
Sort of. In the case of a turboprop, the largest component of the engine's thrust is generated by the propeller. What thrust the actual exhaust makes in a turboprop is very small compared to the screw prop.
Yep. Essentially, that's what a turbo prop is: A jet engine with a propeller attached to it. There is a gear box in between the prop and engine because jets spin waaay faster than a prop should.
LED it is! Whelen is a sponsor of all the nav lighting, beacon and wingtip strobes. Did you see the take off and high speed pass clips we uploaded in the past 24hrs?
hehe, the LED caught my eye, theres a V-tail Bonanza with LED beacons that comes in here every once in a while......they really catch your eye when your used to the normal types
beautiful and yes that's the sound of a turboprop engine but I guess it was started on feather cuz there was no wind & the propellers look in the feather config. I can't believe its on that small aircraft and I hope is made of 2024T or carbon fiber to withstand the stress loads at high speeds. There's no sexier sounds then turbine engines all kinds, makes my heart beat.
Yep. Ken Erickson, is one of the world's best aerobatic flight instructor and an amazing pilot. He has worked side by side with Sean Tucker, Wayne Handley and Rocky Hill. He knows all to well the task at hand with flying an aircraft with a positive thrust to weight ratio (1.5:1)!
That's just an engine with wings.

nice vid of a nice plane. can you tell me why turboprops are always started with blades fully feathered.
are they feathered to make them stop faster after turning off the engine?
