Anyone know what it is/was? The figure on the Wikipedia page claims that it would have been better than a modern turbofan, which I find hard to believe.

Also, for that matter, anyone know how much fuel a -162 could even carry?

Thanks.

The He 162 had a main tank behind the pilot which held 695 liters (183,60 gal.), plus two 180 liter auxiliary tanks in the wings (47,55 gal. each). It could fly for an hour, more or less.

Dux, those would be US gallons rather than real gallons?

join the normal side allready- liters, kg's, km/h
no fuss at all

quick question for all US engeneers out there: how can you think in fractions, like 13/16 of an inch? I dont know... 13,5 mm sound a lot better... http://forums.ubi.com/images/smilies/partyhat.gif

All of the early jets were extremely thirsty because they had very low overall pressure ratios.

Thanks. That yields a SFC of 2.09lb/lb*hr, which makes WAY more sense than the other numbers I had found.

Thanks for the info, you too Dux.

Brown states that it was 20 minutes at sea level but that this could be extended to 57 minutes at 36000 feet. Brown's - Wings of the Luftwaffe has the main tank at 153 imp gallons 695 liters, and two (ungauged wing tanks) of 39.6 Imp gallons/180 liters each.

From the chapter on the He-162, page 164 World War Two Fighting Jets.

"The other fundamental weakness stemmed from the aircraft's very short endurance when flying at high speed: a mere 30 minutes at sea level or 48 minutes at 20,000 feet, and that was without any operational reserve in case a diversion was necessary due to bad weather or the presence of enemy aircraft over the base airfield. Several He 162s were lost because their pilots failed to get them back on the ground before the fuel ran out."

Life is always more complex. The best answer is that it depends on how hard you step on the gas. Just like your car.
