Blip Switch

[vx111vx111swift]

Having  a hard time assigning the blip Switch to  air craft. I have 3 that work  . Now no others will take the input.  Is it me or am I doing something wrong...

[RNAS10_Mitchell]

To my knowledge, it's only available for the Camel , tripe, Dr1, and perhaps D8.

Only ever used on rotary engines. It relies on their inertia to work...

ok   thanks . I read somewhere, all ww 1 planes had them.   Glad itd nothing I was doing incorrectly... Thanks again for the answers..

I think it also only has a use on rotaries, since inline engines can be set to a low-enough idle RPM that they don't produce much force.

When on the subject, what are good use of the blip switch? To turn of the tourqe when turning opposit of the way the engin turns? Dr1 and camel to my knowlege turns way better one way than the other? ?

Cuts ignition IIRC. Most rotaries rotaries were in essence on / off vs the throttleable inlines. As petrol continued to flow while the ignition was cut I read somewhere that it could build up in the engine area in liquid / evaporated form and potentially detonate when the blip switch was released and the spark renewed.

In this game, the blip switch has litte use, as all rotary engines have a fully „working“ throttle. Rotaries don‘t have a carburettor as we know them today, hence power regulation is, depending on model, more or less problematic. In case of the Monosoupape (like on the N28), it is even outwardly impossible to regulate piwer by means of restricting airflow. In that latter case, power can ONLY be regulated by shorting the magneto circuit of a set of individual (throttle: 4 steps/modes IIRC) or all (blip switch) cylinders.

 

As mentioned above, in most cases getting to an idle that for instance allows for a safe/decent landing was difficult to achieve. Cutting the ignition of all cylinders by sporadic and quick grounding of their respective magneto circuits was basically a hack to achive that without having the engine off in a way that would require a bit of time for a restart. As fuel still flows in cylinders that do not fire, this fuel is ejected into the engine cowling, waiting to be ignited when you least want it in case you are using the blip switch a but much.

Yes there is that.

 

It's also useful during (three point) landings to control your airspeed (or in any other situations for that matter). Even with the "throttle" shut there tends to be enough power that your flare can result in ballooning. So you cut the ignition. Now you could just do that through shutting the engine down and gliding for your final approach but using the blip switch instead allows to put the power back on quickly when you need to.

 

It's also useful during dives to avoid over speeding the engine as again even with the throttle shut you can easily exceed the maximum revolution in some dives. Though there are other methods to prevent over speeding (rich mixture trick) that some people find work better for them than using the blip switch. If you hold the switch for too long it's going to shut down the engine but even releasing for about quarter second is enough to keep the engine from doing that.

 

At least this is my experience with regards to the Sopwith Camel. The same uses are possible for the Sopwith Triplane but it's much less prone to over speeding (strangely must have a different airscrew despite the same engine) and seems easier to choke the engine from prolonged use of the switch.

Thx thats really helpfull. I have avoided the camel and dr.1 because of that constant up pitching they have. Now that we got the custom pitch input i have been flying them more and can finnaly understand why they where liked so well by their users ?
