Average fuel consumption is about 950 lb. per hour for a 7,765 lbf engine on a G280, to be compared to 875 lb. per hour for a 4,420 lbf TFE731 on a G150. [3] More than 3.5 million flight hours have been logged till October 2017, and the 2,000th engine should be delivered in 2018. [2] Honeywell maintenance program is $447 for two engines per ...
Here is a similar formula from the 67th edition of the CRC handbook. Note that the form of this formula as given is a fit to the Clausius–Clapeyron equation, which is a good theoretical starting point for calculating saturation vapor pressures:
Methanol fuel is an alternative biofuel for internal combustion and other engines, either in combination with gasoline or independently. Methanol (CH 3 OH) is less expensive to sustainably produce than ethanol fuel, although it is more toxic than ethanol and has a lower energy density than gasoline.
In other words, for the same energy content as one liter or one gallon of gasoline, one needs 1.6 liters/gallons of ethanol and 2.1 liters/gallons of methanol. The raw energy-per-volume numbers produce misleading fuel consumption numbers, however, because alcohol-fueled engines can be made substantially more energy-efficient.
The engines involved in the July and September incidents had 154 and 230 cycles, respectively, while the October failure occurred to an engine with 1,654 cycles since new but within 300 cycles after an electronic engine-control update. Pratt & Whitney recommends inspections on engines with up to 300 cycles after the update.
More than 3,400 engines have been delivered. [5] In 2014, 2,976 civil engines were installed. [6] In 2017, the AE 3007 in the ERJ family had flown over 53 million hours and over 44 million cycles. [7] It was flown for more than 60 million hours. [8] The engine is manufactured at the Rolls-Royce North America engine plant in Indianapolis ...
Two people are dead after a plane crashed into a building near the Daniel K. Inouye International Airport in Honolulu, according to reports. At around 3:15 p.m. local time on Tuesday, Kamaka Air ...
The fuel cartridge stores the methanol fuel. Depending on the system design either 100% methanol (IMPCA industrial standard) or a mixture of methanol with up to 40 vol% water is usually used as fuel for the RMFC system. 100% methanol results in lower fuel consumption than water-methanol mixture (Premix) but goes along with higher fuel cell system complexity for condensing of cathode moisture.
