Time between overhauls (abbreviated as TBO or TBOH) is the manufacturer's recommended number of running hours or calendar time before an aircraft engine or other component requires overhaul. [ 1 ] On rotorcraft , many components have recommended or mandatory TBOs, including main rotor blades , tail rotor blades and gearboxes .
IHI started development work on the high bypass ratio turbofan engine in 1998, based on the low bypass ratio engine XF5-1. and the first prototype XF7-1 was tested from 2000 to 2002. The flight test XF7-10's testing started in 2002.
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 ...
For most unpowered aircraft, the maximum flight time is variable, limited by available daylight hours, aircraft design (performance), weather conditions, aircraft potential energy, and pilot endurance. Therefore, the range equation can only be calculated exactly for powered aircraft. It will be derived for both propeller and jet aircraft.
Kawasaki Heavy Industries Aerospace Company (川崎重工業航空宇宙カンパニー, Kawasaki Jūkōgyō Kōkūuchū Kanpanii) is the aerospace division of Kawasaki Heavy Industries (KHI). It produces aircraft , space systems , simulators , jet engines , missiles , and electronic equipment .
Aircraft engine performance refers to factors including thrust or shaft power for fuel consumed, weight, cost, outside dimensions and life. It includes meeting regulated environmental limits which apply to emissions of noise and chemical pollutants, and regulated safety aspects which require a design that can safely tolerate environmental hazards such as birds, rain, hail and icing conditions.

In rocketry, a heavier engine with a higher specific impulse may not be as effective in gaining altitude, distance, or velocity as a lighter engine with a lower specific impulse, especially if the latter engine possesses a higher thrust-to-weight ratio. This is a significant reason for most rocket designs having multiple stages.
