Research into the next generation of commercial jet engines, high-bypass ratio turbofans in the "10-ton" (20,000 lbf; 89 kN) thrust class, began in the late 1960s. Snecma (now Safran), who had mostly built military engines previously, was the first company to seek entrance into the market by searching for a partner with commercial experience to design and build an engine in this class.
An Airbus A380 deploying thurst reverser while landing, blowing water from the wet surface and making the reversed air flow observable.. Thrust reversal, also called reverse thrust, is the temporary diversion of an aircraft engine's thrust for it to act against the forward travel of the aircraft, providing deceleration.
The DC-8-41 and DC-8-42 had weights of 300,000 and 310,000 pounds (140,000 and 140,000 kg) respectively, the 315,000-pound (142,880 kg) DC-8-43 had the 1.5° flap setting of the -33 and introduced a 4% leading-edge wing extension to reduce drag and increase fuel capacity slightly – the new wing improved range by 8%, lifting capacity by 6,600 ...
The reverse-thrust ratio (ratio of backward engine thrust to forward reverse thrust) can be as high as 84%. [6] However, this result is obtained with a cowl to attach air flow in a 7° angle and a large enough "target" (deflector door) installed. A reverse-thrust ratio of 55% can be reached on a simple target without the cowl. [7]
In addition, LAN signed with Pratt and Whitney to power up to 25 option aircraft. If LAN exercises all options it would mean an additional 56 (50 installed and six spare) engines. [citation needed] [needs update] Prior to the LAN order, 84 CFM56-5 powered Airbus A318 aircraft had been ordered, with 28 currently in service as of December 2005.
Over the first half of 2019, CFM revenues were up by 23% to €5.9 billion with 1,119 engine deliveries; declining sales of CFM56 (258 sold), more than offset by LEAP (861 sold). [5] Recurring operating income rose by 34% to €1.2 billion , but was reduced by €107 million ( US$118 million ) due to the negative margins and initial costs of ...

The monobloc nozzle assembly is installed behind two Olympus 593s. The nozzles are shown in different operating positions to illustrate take-off (right) and landing reverse thrust (left). They are partially closed for take-off to reduce sideline noise. [25] They are fully closed to deflect the exhaust partially forward to produce reverse thrust.
