La NASA presenta nuevo concepto de avión supersónico "bidireccional"

lunes, 3 de septiembre de 2012

Uno cree que ha visto casi cualquier tipo de concepto de "cacharro" volador, cuando llega la NASA y le sorprende con una especie de suriken ("estrella ninja") supersónica.

New NASA project: Silent and Efficient Supersonic Bi-Directional Flying Wing

Description: We propose a Phase I study for a novel concept of a supersonic bi-directional (SBiDir) flying wing (FW) that has the potential to revolutionize supersonic flight with virtually zero sonic boom and ultra-high aerodynamic efficiency. The SBiDir-FW planform is symmetric about both the longitudinal and span axes. For supersonic flight, the planform can have as low aspect ratio and as high sweep angle as desired to minimize wave drag and sonic boom. For subsonic mode, the airplane will rotate 90deg in flight to achieve superior stable aerodynamic performance. The conflict of subsonic and supersonic aerodynamic performance of conventional fuselage-wing configuration is hence removed. The preliminary CFD simulation for a SBiDir-FW business jet (BJ) at Mach numbers of 1.6 and 2.0 indicates that the configuration generates no N-wave sonic boom on the ground at a high lift to pressure drag ratio L/Dp of 16. The superior supersonic aerodynamic performance is benefited from the sharp nose and ultra-slender body with a low aspect ratio of 0.33, which translates to a very high subsonic aspect ratio of 33 for high subsonic performance. This proposal has three objectives: 1) design refinement of a supersonic SBiDir-FW BJ configuration using CFD; 2) mission analysis assisted with CFD simulation for the supersonic SBiDir-FW BJ to study the feasibility; and 3) wind tunnel testing of the SbiDir-FW BJ to verify its supersonic aerodynamic performance and sonic boom signature. The research team is highly qualified to perform the proposed tasks.

Boeing to Establish Avionics Maintenance, Repair and Overhaul Center in Korea

Affordable MRO services to focus on avionics components for F-15Ks
Facility in Yeongcheon Industry District of Daegu-Gyeongbuk Free Economic Zone supports Aero Techno Valley establishment

DAEGU, Republic of Korea, Sept. 3, 2012 -- Boeing [NYSE: BA] has signed a memorandum of understanding with the Korean province of Gyeongsangbuk-do and the city of Yeongcheon to establish an avionics Maintenance, Repair and Overhaul (MRO) facility in the region that will service avionics components for the Republic of Korea Air Force (ROKAF) fleet of F-15K Slam Eagles.

"Boeing continues to improve its services by bringing them closer to our customers, reducing turnaround time and costs for mission-essential components," said Joe Song, vice president of International Business Development - Asia-Pacific for Boeing Defense, Space & Security. "Over the past half century of working in partnership with the Republic of Korea, Boeing has come to know Korea's strong infrastructure and the excellent knowledge and talent base of its people and industry. We can tap into that as we expand our presence locally and grow our operations while supporting Korea's development objectives."

The facility, which will be located in the Yeongcheon Industry District of Daegu-Gyeongbuk Free Economic Zone, will support the area's Aero Techno Valley vision of a high-tech aerospace industry corridor and expanded in-country avionics capabilities. The location is close to Daegu Air Force Base and ideally suited for the Slam Eagle work as part of Boeing's Performance-Based Logistics (PBL) program.

"Partnering with a global leader like Boeing will help attract investment from local and international aerospace companies, secure government support and fuel our plans to establish an aviation-parts cluster here," said Gyeongsangbuk-do Gov. Kim Kwan-yong. "Adding high-tech, value-added business such as avionics to the Gyeongsangbuk-do region will open new doors for local industry, create more jobs for high-skilled workers and support technological competitiveness."

Boeing completed the on-schedule, on-cost delivery of F-15K Slam Eagles to the ROKAF in April. The company continues to support the ROKAF fleet through a long-term, affordable PBL sustainment contract. Korean supplier-partner Hyundai Glovis provides in-country logistics handling and supply chain distribution for the F-15K PBL program.

Boeing's history of cooperation with the Republic of Korea includes productive partnerships in the commercial and defense aerospace markets. The company employs nearly 190 highly skilled workers in Seoul, Busan, Gimpo, Sacheon, Seosan and Daegu. Today, Boeing works with nearly 20 Korean companies and spent more than $250 million with them in 2011, maintaining Korea's position in the top quartile of nations with which Boeing does business.

Boeing Fatigue Test to Validate Predicted Life of B-1 Bomber Fleet

TUKWILA, Wash., Aug. 30, 2012 -- Boeing [NYSE: BA] has begun a five-year fatigue test on the wing of a U.S. Air Force B-1 bomber to validate the predicted life of the bomber fleet, currently forecasted to be 2050. The test also will reveal potential areas of concern for which Boeing and the Air Force can develop maintenance and repair plans.

"This comprehensive testing is a proactive way for Boeing to meet its mission of keeping the B-1 bomber fleet ready and viable," said Rick Greenwell, Boeing B-1 program director.

Boeing and the Air Force also plan to fatigue-test a B-1 fuselage at Boeing Tukwila beginning in November 2013.

Airplane Seat to Provide Custom-Controlled Climate [VIDEO]

Alongside long security lineups and baggage
fees, one of the biggest pet peeves associated
with air travel is unpredictable temperatures on
board planes.
While the climate is freezing for her, it's way
too hot for him. To remedy this, researchers at
Germany's Fraunhofer Institute for Building
Physics IBP are developing an airplane seat that
will let occupants adjust temperatures to fit
their preferences.
