In-Air Re-Starts

[SIK1]

Sluggish having seen rotary engine aircraft do this numerous times at Rhinebeck Aerodrome, and after speaking with the pilots. I can tell you that it is common, (several had the "Blip" switch right on the stick) and was done frequently. The only thing your trying to do is continue this discussion in a different thread. If you have the chance, go to Rhinebeck http://www.oldrhinebeck.org/ It's an incredible place and everyone's more than willing to talk to you at great lengths about early airplanes.

BTW in reality the prop does not stop spinning until a much lower speed. So if your going to "wish" for anything it might be that the animation keep the prop spinning until the aircraft slows down to 10mph or so.

I would really like to go to Rhinebeck Aerodrome. If I'm ever anywhere near it in the summer time I'm going. Damn the torpedoes full speed ahead.

[sluggish]

I've got a sweet answer for you.
Same scenario, 2k, turn off engine, pull it up into a loop. (to get to almost 0 airspeed) so the prop stops.
I tried it your way but in level flight about half the time the prop wouldn't stop.

Point nose down, inside 3 seconds the prop is spinning again. All you did was apply airspeed.
That is the way they worked, accept it. The force of the air at 100 mph is enough to turn over the engine.

Now, care to continue digging that hole or have you had enough yet?

Here's what I want you to try.

Take off in a Dr.1 and get it to a reasonable altitude.  Press X to engage level flight.  Push the E button.  After the stall horn start honking really loud, the prop will stop turning.  Now...  Press the E button again.  Now ask yourself if the resulting action is possible in ANY WW1 era aircraft.

If the prop stops pushing the E button should not restart the engine.  I don't know what hole you're talking about, this is just common sense.

NOW...  If you can nose over and get the prop spinning again, pushing the E button WOULD restart the engine.  BUT... If the prop isn't spinning there is NO WAY you're going to get that engine started.  You can deny the obvious all you want, or change the scenario BUT, if the prop's not spinning, the engine ain't starting.

A blip button is one thing.  This is something totally different.

Now you're not making any sense at all.  Please stay on topic.

sluggish,
A blip switch is nothing more than a switch that turns off the ignition. These engines use magnetos which are very reliable, and easy to get spark out of. If you have ever seen an WW1 rotary you know that they will kill the ignition entirely at times. It doesn't take a lot to get these engines turning over and once it's turning over add spark and presto it's running. Just like magic. Baumer even states "BTW in reality the prop does not stop spinning until a much lower speed." I highlighted it in his original quote for you. If you don't know, Old Rhinebeck Aerodromes is one of the few places on earth where they still fly real, and accurately created facsimiles of WW1 aircraft. If Baumer says he talked to some of the pilots I believe him. I've also done research on my own, and have a small understanding of how these engines work and how engines work in general. 

Reading comprehension is a skill. You might want to practice.

in 2 seperate threads now you have continued to dig yourself into a hole you can't get out of.

You can't win this argument, because your wrong, your looking at it wrong, and you refuse to accept that someone else is right. Hence the hole digging comment, same as in the other thread. And it IS on topic because you refuse to accept the correct answers that you've been given.

Now you're not making any sense at all.  Please stay on topic.

Once more, slowly, from the top.

Your flying along in your DR1, you hit the blip switch, which cuts the spark to the engine.
Engine is still turning over because of air pressure to the prop. You pull up into a loop to lower the airspeed, or hold it level till it falls into a flat stall. Either way, your choice. Airspeed drops enough so the prop stops.

Point the nose down, inside of 2 seconds you've regained enough airspeed that the motor and prop are turning over again. Release the blip switch, allowing spark from the magento to go to the spark plug and the motor is running again.

I haven't restarted the motor with some non existent electrical starter. I used the wind pressure on the prop to turn the motor over and stopped interrupting the spark.

Your wrong in your assumption that it needed an electric starter to turn the motor over.
Your wrong in your assumption that anyone would leave the engine off "That long" at any rate, long enough for it to stop.
Your wrong in your assumption that once stopped it would not restart.


Now, your at the bottom of a BLOODY big hole, ready to quit yet? Or are you going to keep digging?
I didn't want to pick on you, still don't. But you won't accept the truth when several people point it out to you.

Once again typing real slow...

If the prop stops pushing the E button should not restart the engine.  I don't know what hole you're talking about, this is just common sense.

NOW...  If you can nose over and get the prop spinning again, pushing the E button WOULD restart the engine.  BUT...

First rule of flight. Fly the plane first.

If you are such a poor pilot that you hold the blip switch long enough for the prop to stop turning, then hold the nose up so that the prop will not start to turn.( The prop will start to turn, or windmill due to aerodynamic forces if the nose is lowered and airspeed builds up.) Then you deserve to fall out of the sky and crash.

Keep digging.

Now we need a dead horse beating smiley.

[Baumer]

OK Typing real slow and in big letters......

Please show some evidence that, in real life the propeller (and engine) stop spinning when you cut out the engine at 50mph or even 40mph.

Like I posted previously, the propeller will keep spinning at much slower speeds than what you "see" in AH.

[FLS]

It seems reasonable to wish that a stopped engine can't be restarted unless the propeller is spinning. That wasn't the original post but it may have been the original intent.  I doubt most people would ever notice if this change was made but I don't see where there's anything to argue about.

[2ADoc]

I speak from experience, you can shut the engine off, have the prop stopped, and windmill the engine to get it started.  I did it in a PA-38-112, or Piper Tomahawk, I have also done it in a Pietenpole Aircamper, with a 5 cylinder Lambert.  In the Tomahawk, pull the mixture back, kill the enigine and raise the nose till the prop stops, to restart it Push the mixture in, lower the nose the prop will start turning again, and it fires right up.  In the case of the Pietenpole, Turn the mags off, raise the nose, the prop stops at about 65, it was a high compression engine.  When you get ready to start it, lower the nose, turn the mags on, build up airspeed, as it goes thru 70 Kts, you wish you had not done this, at about 75 the prop starts to windmill, count 3 or 4 blades, and it fires right up, hopefully.  PS dont tell my dad that I did that in a Tomahawk, he would kill me, and that has been 18 years ago, but it sure did impress the girl I was flying with.

Turn prop off, go into zoom, prop stops, takes about 100 or more mph dive to restart.
