Carburetor heat info?

[Nato]

I appear to get carb icing flying through clouds in a hurricane/spitfire but have no means to de-ice.The Hurricane is carburated , any thoughts short of dont fly through clouds.Thanks

Merlin Carb throats were warmed continuously by a jacketed design no separate Carb heat was fitted or required.

Thank you for the clarifing , much appicated.

So why does engine start to run poorly after only a hand full of seconds in a cloud??

[IvanK]

Me thinks Prop icing.

[bongodriver]

Yep...prop ice or maybe even ice forming around the air intake scoop.

The cockpit ices over as well. Is this weather effect modelling correct as it occurs at low altitude, between July and September over the UK (Summer early Autumn)?

Take a biker for example, why do they pack so much clothes even if it has 30°C or more outside? Because of their Speed! One biker said: "As a rule of thumb, for every 10 kph, the temperature drops 1°C."

Now imagine going around 500kph, with an ambient temperature of only around 20°C.

500kph In a 'CLoD' SpitMk1a?......if only but I take your point! :grin:

500kph is only 270kts....spit should do that.

but speed has no effect, it's only OAT and visible water vapour, in the company I fly for (prob based on an industry standard) airframe icing can be anticipated between +10 deg to -40 deg and then only when in IMC or any precipitation, we like to avoid using anti-ice because it makes it harder to slow dow during descent, we certainly manage to fly faster than 500kph in the Learjet.
