Si podéis, os recomiendo este documental precisamente sobre ello, http://www.netflix.com/es/title/81272421 que explica bastante bien las razones.

Con esto podréis entender en buena parte lo sucedido con el KC46 y con el 737MAX.

DAYTON, Ohio—More than six years after the Air Force identified the first serious deficiency on the KC-46 tanker, six Category 1 deficiencies still remain and a seventh was downgraded to Category 2 in April, said Col. Leigh Ottati, chief of the KC-46 program office—the first public announcement of that development

Ottati detailed the deficiencies still plaguing the Pegasus during the Life Cycle Industry Days conference last week and shared updated timelines for resolving some of them.

JetZero is developing an ultra-efficient Blended Wing Body jet with unprecedented performance. Working with the US Air Force, NASA and the FAA for entry-into-service by 2030.

NASA and Boeing flew an 8.5%-scale BWB demonstrator in 2007, known as the X-48B. Unlike that design, the JetZero aircraft will be a full-scale flying prototype. The USAF aims to fly the XBW-1 by 2027.

“It’s not just a more fuel-efficient cargo or tanker aircraft,” says Major General Albert Miller with Air Mobility Command (AMC), which oversees the USAF’s fleet of transports and in-flight refuellers. “We’re going to have to have tankers flying in weapons engagement zones,” Albert notes of potential conflicts with advanced adversaries like Russia and China.
While a BWB design has been floated as a possibility for NGAS, Miller says it is “premature” to assume the XBW-1 – or any other BWB type – will be the ultimate choice for the stealth tanker.

The JetZero Blended Wing is the biggest leap in commercial aircraft architecture since the dawn of the jet age and the best first step toward the ultimate goal of zero-carbon emissions aviation. The aircraft will launch in 2030 with 100% SAF compatibility, and the internal volume to accommodate zero-carbon emissions hydrogen.
The JetZero Z4 BWB, which the company showcased at the Paris air show, will deliver a 50% fuel-burn reduction and weight savings over Boeing 767s and 787-8s, the company said.

Cuidado, que no. Esa no es una propuesta para el furtivo, es una propuesta para el "blended body", que parece lo mismo pero no lo es...

Atticus escribió: Los fuselajes integrados son muy interesantes aerodinamicamente, pero un dolor de huevos en cuanto empiezas a meter en la ecuacion cosas como la presurizacion del interior, los tiempos de evacuacion (en aviones de pasaje) y, aunque sea algo mas estetico que otra cosa, el acceso a las ventanillas desde las plazas interiores. Este concepto podria tener una buena vida militar, pero es discutible su adopcion en el mercado comercial.
