Boeing 737 MAX Gets New Orders

Image
Boeing easily beat rival Airbus in orders for new planes last month, but Chicago-based Boeing trailed its European rival in delivering planes to airline customers. Boeing said that it took orders for 31 planes in July while 17 others were canceled, resulting in a net gain of 14. That compared with two orders for Airbus. It was Boeing’s sixth straight month of positive net orders after seeing cancellations exceed orders for most of 2020. Boeing has reported 270 net orders so far in 2021. Brazil’s Gol ordered nine 737 Max jets last month and Dallas-based Southwest Airlines ordered six. Boeing delivered 28 planes in July, including nine 737 Max jets sent to Irish airline Ryanair. That fell short of Airbus, which delivered 47 planes last month. For the year, Boeing has delivered 184 planes, more than all of 2020. This despite the halt in shipping its 787 jet because of production flaws in the fuselage and nose. Last month, the company said it will cut production of 787s. Deliveries are cri...

Reduced Aircraft Mass 1. Reduced structural and payload weight Some of the ideas dealt with in other sections may have relevance here: the use of ground power augmentation (section 2.2) may serve to reduce engine thrust or the use of detachable or ground located undercarriages (section 4.1.3). However, the most effective approach to a better relationship between power, weight and payload seems to rest with new concepts for the aircraft design. The concept that appears to receive most effort to bring it forward is the Blended Wing Body [BWB]. The savings of drag achieved by its tail-less nature are significant and the L/D function in designs being studied is about 15% higher than current design conventions. Reducing the structural weight of a given concept will bring about benefits dependent upon its operational use. Broadly based figures suggest that the percentage taken off the weight of the aircraft, engines and systems will produce a percentage saving in fuel burn per tonne-k...
