In-Air Re-Starts
« on: March 18, 2010, 10:39:25 AM »
None of the WW1 planes had electric starters.  If you shut your engine off in flight, and are going slow enough to allow the prop to stop turning (whatever speed that may be), you should not be able to restart the engine.

Agree!

In WW2 or WWI I do not believe it was something any sane pilot would do in combat.

But it's a subject that's been beaten to death literally since day one and I do not believe
it is something HTC will change

Well, on that note, there should also be a 20-30 minute wait to re-up then...........

Do you imagine the "so slow the prop is not turning" speed to be faster or slower than the power off stall speed?

Hmmmmm wonder how that equates with "blip" switches since many WWI aircraft didnot throttles???

A momentary kill switch would actually be a nice feature on planes that had them...

Notice that even when sitting on the ground or taxiing, this pilot spends more time with his engine off than on...

I've read at-least two accounts where pilots in world war 1 frequently turned of thier radiels in order to steady thier planes in a dive when firing against an apponent.
I beleieve one was richtofen.

He did make an adjustment about 7-8 years ago when turning on/off the engine was used by a lot to turn tighter, it no longer gives you the benefits it once had.

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.

Most WWII planes also didn't have electric starters. Some used cartridge system, others a hand crank flywheel. Yet I don't see you asking for those to be fixed.

Fact remains at flying speeds the prop is going to windmill, which means the engine is turning over.
You turn on the spark and you'll have ignition, so engine is back on producing torque.
As far as asking for the engine not to be able to be restarted, shrug. Who cares?

No one who is using the engine blip switch is going to get that slow.

Nor leave it off long enough for the prop to quit spinning. Except at takeoff and landing.

So if it doesn't really effect flight, or combat, whats the point?

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?

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.
