Tango Posted December 31, 2008 Posted December 31, 2008 (edited) Disregard - found it. :) At takeoff power (2200 hp), each engine burns 3 tons/hr. Best regards, Tango. Edited December 31, 2008 by Tango
AlphaOneSix Posted December 31, 2008 Posted December 31, 2008 (edited) 3 tons as in 3,000 kilograms? As in roughly 2400 liters per hour? That sounds wildly inaccurate. Where did you get that number? It should be more like 450 liters per hour per engine, or roughly 550 kilograms per engine per hour. Edited December 31, 2008 by AlphaOneSix
Tango Posted December 31, 2008 Author Posted December 31, 2008 (edited) The aircraft can carry 1800 kg of fuel internally. Starting with a 1/2 fuel loading, we were able to fly for approx. 45 minutes (mainly in the hover). 1,800 kg x 0.5 = 900 kg fuel onboard. That makes for an actual total fuel burn of 1.2T per hour, approximately (I didn't time it exactly). According to the book, it states the fuel burn is 137 g per hp per hour. 137 x 2,200 hp = 301,400 g or 3,014 kg/hr, or 3T/hr, PER ENGINE. Each engine measures 2055x650x728mm and develops 2,200 hp at take off with a fuel consumption of 137 g/(hp • hr). Forgive me if I have somehow mis-read the • . I'm still burning more fuel than you say I should. Best regards, Tango. Edited December 31, 2008 by Tango
Cyb0rg Posted December 31, 2008 Posted December 31, 2008 301400 g = 301 Kg not 3014 [sIGPIC][/sIGPIC] Asteroids ____________________________________________ Update this :D
Tango Posted December 31, 2008 Author Posted December 31, 2008 (edited) OOPS................... Yeah yeah... I see the problem, and why it is burning more fuel (WEAPONS LOAD :doh: ). I need some sleep!! Best regards, Tango. Edited December 31, 2008 by Tango
RvETito Posted December 31, 2008 Posted December 31, 2008 Average fuel consumption of TV3-117VMA is 330 kg/h. "See, to me that's a stupid instrument. It tells what your angle of attack is. If you don't know you shouldn't be flying." - Chuck Yeager, from the back seat of F-15D at age 89. =RvE=
McVittees Posted December 31, 2008 Posted December 31, 2008 Average fuel consumption of TV3-117VMA is 330 kg/h. Is a helicopters fuel consumption effected much by altitude? By this I mean, how long a journey must I be undertaking for it to be worth flying high (and by high I mean say 3000m) or will I get just as good performance staying in the weeds?

RvETito Posted December 31, 2008 Posted December 31, 2008 Of course it is affected but to a much less degree because they don't fly higher than 4000m on book. Generally speaking for long range ferry flights it's worth climbing and cruising at 3000m for example. "See, to me that's a stupid instrument. It tells what your angle of attack is.

zdXu Posted January 21, 2010 Posted January 21, 2010 Average fuel consumption of TV3-117VMA is 330 kg/h. My sim-expierence (i am not an expert) is: Average(!) fuel consumption without weaponload = 550 Kg/h. When the 110 kg-minimum-emergency-thereshold-warning starts then you have ca 12 minutes to find a landing-place.
