Argentina compraría helicópteros Rusos

November 21, 2008

Por: Juan Manuel Barragán

El Estado Mayor Conjunto de las Fuerzas Armadas Argentinas, se encuentra analizando la compra de dos helicópteros Kamov Ka-32C para ser utilizados en apoyo a las futuras Campañas Antárticas de Verano, embarcados en buques del Comando Naval Antártico. También se esta evaluando la compra de tres helicópteros medianos KAZAN/Mil Mi-17 para ser operados por la Fuerza Aérea Argentina. 

El Ka-32C tiene capacidad de carga interna de 3,700 Kg ó 5,000 Kg de carga externa, mientras que el Mil Mi-17 posee 4,000Kg y 4,500 Kg de carga respectivamente. Este ultimo helicóptero tiene la particularidad de contar con la autonomía necesaria para que en vuelo ferry, con la máxima carga interna de combustible en la cabina pueda realizar el cruce del Drake, pudiendo llegar en vuelo hasta la Base Marambio (Antártida Argentina).

De este modo se recuperaría la capacidad de unir en vuelo el continente blanco con aeronaves de alas rotativas, desde la baja de los Boeing-Vertol 308 Chinook de la Fuerza Aérea Argentina. El primer vuelo entre el Continente Americano y el Antártico se realizo el 30 de noviembre de 1980, cuando los Chinook matriculas H-91 y H-92, unieron Río Grande (provincia de Tierra del Fuego) con la Base Marambio. En este vuelo se recorrieron 1.325 Km en 6 horas, habiendo recibido apoyo meteorológico en ruta facilitado por el avión KC-130H Hércules, matrícula TC-70 de la I Brigada Aérea “El Palomar”.

Debido a su bajo precio comparado con helicópteros similares occidentales y a su éxito de exportación de 1200 helicópteros a 30 países, es que se evalúa la compra del Mil Mi-17 para la Fuerza Aérea Argentina. En caso de que se concrete la misma, esta seria la primera compra de equipamiento militar de origen Ruso.

TSA and American Airlines Initiate Paperless Boarding Pass

November 20, 2008

 

LOS ANGELES, CA–(Marketwire – November 20, 2008) – The Transportation Security Administration (TSA) and American Airlines announced today the launch of a Paperless Boarding Pass pilot program at Los Angeles International Airport (LAX). It will allow passengers to receive boarding passes electronically on their cell phones or PDAs, which will then be scanned by TSA security officers at the checkpoint and eliminate the need for a paper boarding pass.

Each paperless boarding pass will display a two-dimensional barcode along with passenger and flight information that will identify the traveler. TSA travel document checkers will use mobile scanners to validate the authenticity of the paperless boarding pass sent to American Airlines passengers as well as the traditional boarding passes. The new technology heightens the ability to detect fraudulent boarding passes while improving customer service and reducing paper use.

“The deployment of the paperless technology signifies TSA’s ongoing commitment to develop and execute new technologies within aviation while enhancing security,” said Larry Fetters, federal security director, LAX. “We are thrilled to be able to expand this pilot program and deploy new technology that will help our document checkers validate authentic boarding documents.”

Last week, American Airlines introduced these new mobile boarding passes at Chicago’s O’Hare International Airport and debuted the technology this week at LAX and John Wayne Orange County (SNA) airports as well.

“Mobile boarding via AA.com is the latest way American Airlines is making travel as easy and convenient as possible, especially for our customers on the go,” said Mark DuPont, American’s vice president – Airport Services Planning. “Customers who choose this option can bypass printing a boarding pass at their home, office or even at the airport to board their plane. They can go straight to security and then to the aircraft.”

To use the mobile boarding pass option — either with the traditional desktop version of AA.com or the mobile version — customers must have an active e-mail address where their boarding pass may be sent and an Internet-enabled mobile device where the two-dimensional barcode can be received. Additionally, during the introduction of this new feature, customers may list only one person in their reservation and must be traveling on American or American Eagle nonstop or same-plane direct to a domestic destination from Chicago, Los Angeles or Orange County. Domestic destinations include those within the United States as well as the U.S. Virgin Islands and Puerto Rico.

The mobile boarding pass process is simple: When customers check in for their flight using American’s Web site, AA.com — either the desktop or mobile versions — they have the option to receive their boarding passes on their cell phones or PDAs. If this option is selected, they will get an e-mail with an Internet link to their boarding pass. The mobile boarding pass contains a two-dimensional barcode that can be scanned at TSA security checkpoints and at American Airlines gates. At the airport, customers simply scan their cell phone or PDA screen when going through security (proper identification must be presented) and when boarding, just as they would a traditional paper boarding pass.

Customers wishing to check bags can also use the new option by scanning the boarding pass on their cell phone or PDA screen at American Airlines self-service machines, ticket counters, or curbside check-in facilities.

Business Jets Winging their Way out of the Financial Crisis

November 20, 2008

DUSSELDORF, GERMANY–(Marketwire – November 20, 2008) –
2nd International IIR Conference “Business Aviation” from 20th to 22nd January 2009, Hotel Louis C. Jacob, Hamburg

Frankfurt/Hamburg, November 2008. Despite the financial crisis, business jets have become more and more popular. According to a study by the supplier Honeywell Aerospace, the development of the market for business jets is disproportionate. The industry thus expects further growth in 2009. The production will be working to capacity for the following three years and the demand will still be high (AeroBrief, 2008-10-16).

“It is no special luxury anymore to fly with a business jet today. It has become a normal, fast means of transport,” agreed Dr. Bernd Gans, President of the German Business Aviation Association (GBAA) (Focus, 2008-11-05). Gans chairs the 2nd International IIR Conference “Business Aviation”, which takes place from 20th to 22nd January 2009 in Hamburg. The event will discuss the new regulations of the European Aviation Safety Agency (EASA), the project “Single European Sky” (SES) of the European Commission and changes in corporate financing of planes.

In addition to GBAA President Gans, Eric Mandemaker, CEO of the European Business Aviation Association (EBAA), and Trevor Esling of Cessna Aircraft UK will report on developments on the business air travel market. Ministerialdirigent (assistant secretary) Franzjosef Schafhausen from the Federal Environment Ministry will give a presentation on EU emissions trading and its impact on business air travel and Peter Herr of Beechcraft Aircraft will introduce one of the plane models for business air travel.

NASA Spacecraft Detects Buried Glaciers on Mars

November 20, 2008

PASADENA, Calif., Nov. 20 /PRNewswire-USNewswire/ — NASA’s Mars Reconnaissance Orbiter has revealed vast Martian glaciers of water ice under protective blankets of rocky debris at much lower latitudes than any ice previously identified on the Red Planet.

Scientists analyzed data from the spacecraft’s ground-penetrating radar and report in the Nov. 21 issue of the journal Science that buried glaciers extend for dozens of miles from the edges of mountains or cliffs. A layer of rocky debris blanketing the ice may have preserved the underground glaciers as remnants from an ice sheet that covered middle latitudes during a past ice age. This discovery is similar to massive ice glaciers that have been detected under rocky coverings in Antarctica.

“Altogether, these glaciers almost certainly represent the largest reservoir of water ice on Mars that is not in the polar caps,” said John W. Holt of the University of Texas at Austin, who is lead author of the report. “Just one of the features we examined is three times larger than the city of Los Angeles and up to half a mile thick. And there are many more. In addition to their scientific value, they could be a source of water to support future exploration of Mars.”

Scientists have been puzzled by what are known as aprons — gently sloping areas containing rocky deposits at the bases of taller geographical features — since NASA’s Viking orbiters first observed them on the Martian surface in the 1970s. One theory has been that the aprons are flows of rocky debris lubricated by a small amount of ice. Now, the shallow radar instrument on the Mars Reconnaissance Orbiter has provided scientists an answer to this Martian puzzle.

“These results are the smoking gun pointing to the presence of large amounts of water ice at these latitudes,” said Ali Safaeinili, a shallow radar instruments team member with NASA’s Jet Propulsion Laboratory in Pasadena, Calif.

Radar echoes received by the spacecraft indicated radio waves pass through the aprons and reflect off a deeper surface below without significant loss in strength. That is expected if the apron areas are composed of thick ice under a relatively thin covering. The radar does not detect reflections from the interior of these deposits as would occur if they contained significant rock debris. The apparent velocity of radio waves passing through the apron is consistent with a composition of water ice.

Scientists developed the shallow radar instrument for the orbiter to examine these mid-latitude geographical features and layered deposits at the Martian poles. The Italian Space Agency provided the instrument.

“We developed the instrument so it could operate on this kind of terrain,” said Roberto Seu, leader of the instrument science team at the University of Rome La Sapienza in Italy. “It is now a priority to observe other examples of these aprons to determine whether they are also ice.”

Holt and 11 co-authors report the buried glaciers lie in the Hellas Basin region of Mars’ southern hemisphere. The radar also has detected similar-appearing aprons extending from cliffs in the northern hemisphere.

“There’s an even larger volume of water ice in the northern deposits,” said JPL geologist Jeffrey J. Plaut, who will be publishing results about these deposits in the American Geophysical Union’s Geophysical Research Letters. “The fact these features are in the same latitude bands, about 35 to 60 degrees in both hemispheres, points to a climate-driven mechanism for explaining how they got there.”

The rocky debris blanket topping the glaciers apparently has protected the ice from vaporizing, which would happen if it were exposed to the atmosphere at these latitudes.

“A key question is, how did the ice get there in the first place?” said James W. Head of Brown University in Providence, R.I. “The tilt of Mars’ spin axis sometimes gets much greater than it is now. Climate modeling tells us ice sheets could cover mid-latitude regions of Mars during those high-tilt periods. The buried glaciers make sense as preserved fragments from an ice age millions of years ago. On Earth, such buried glacial ice in Antarctica preserves the record of traces of ancient organisms and past climate history.”

Sikorsky Sales in China Continue to Grow

November 20, 2008


STRATFORD, Conn., Nov. 20 /PRNewswire/ — China Southern Airlines’ Zhuhai Helicopter Company this week accepted two Sikorsky S-76C++(TM) helicopters to support offshore oil projects in the South China Sea and Bohai Bay. Sikorsky is a subsidiary of United Technologies Corp. (NYSE: UTX).

The acceptance follows a trend of civil aircraft sales into the region for Sikorsky. Last month, Sikorsky signed an agreement with the Rescue and Salvage Bureau of China’s Ministry of Transport (MOT) for four S-76C++ helicopters to enhance the MOT’s maritime and search and rescue capabilities, bringing the fleet’s total to eight and making it one of the largest operators of Sikorsky S-76(R) SAR helicopters in the world.

“Sikorsky Aircraft has been busy in China for the past few years,” said Scott Pierce, Vice President, Sikorsky Asia. “In early 2007, we delivered the first S-92(R) helicopter to China, and soon afterwards, sold another S-92 helicopter in the region. Following that, Sikorsky experienced unprecedented growth in China with the sale of six S-76C++ helicopters. The trend is sound evidence of the popularity of Sikorsky products among Chinese customers, and is strong affirmation of our strategy for this region.”

Two of the three licensed offshore oil helicopter operators in China fly Sikorsky helicopters. In addition, two multibillion-dollar Chinese private enterprises have chosen the S-76 C++ helicopter as their corporate aircraft, making the S-76C++ helicopter the first VVIP helicopter of intermediate class introduced into China.

NASA Successfully Tests First Deep Space Internet

November 19, 2008

NASA Logo. (PRNewsFoto/NASA)

WASHINGTON, DC UNITED STATES

PASADENA, Calif., Nov. 18 /PRNewswire-USNewswire/ — NASA has successfully tested the first deep space communications network modeled on the Internet.

Working as part of a NASA-wide team, engineers from NASA’s Jet Propulsion Laboratory in Pasadena, Calif., used software called Disruption-Tolerant Networking, or DTN, to transmit dozens of space images to and from a NASA science spacecraft located about 20 million miles from Earth.

“This is the first step in creating a totally new space communications capability, an interplanetary Internet,” said Adrian Hooke, team lead and manager of space-networking architecture, technology and standards at NASA Headquarters in Washington.

NASA and Vint Cerf, a vice president at Google Inc., in Mountain View, Calif., partnered 10 years ago to develop this software protocol. The DTN sends information using a method that differs from the normal Internet’s Transmission-Control Protocol/Internet Protocol, or TCP/IP, communication suite, which Cerf co-designed.

The Interplanetary Internet must be robust to withstand delays, disruptions and disconnections in space. Glitches can happen when a spacecraft moves behind a planet, or when solar storms and long communication delays occur. The delay in sending or receiving data from Mars takes between three-and-a-half to 20 minutes at the speed of light.

Unlike TCP/IP on Earth, the DTN does not assume a continuous end-to-end connection. In its design, if a destination path cannot be found, the data packets are not discarded. Instead, each network node keeps the information as long as necessary until it can communicate safely with another node. This store-and-forward method, similar to basketball players safely passing the ball to the player nearest the basket means information does not get lost when no immediate path to the destination exists. Eventually, the information is delivered to the end user.

“In space today, an operations team must manually schedule each link and generate all the commands to specify which data to send, when to send it, and where to send it,” said Leigh Torgerson, manager of the DTN Experiment Operations Center at JPL. “With standardized DTN, this can all be done automatically.”

Engineers began a month-long series of DTN demonstrations in October. Data were transmitted using NASA’s Deep Space Network in demonstrations occurring twice a week. Engineers use NASA’s Epoxi spacecraft as a Mars data-relay orbiter. Epoxi is on a mission to encounter Comet Hartley 2 in two years. There are 10 nodes on this early interplanetary network. One is the Epoxi spacecraft itself and the other nine, which are on the ground at JPL, simulate Mars landers, orbiters and ground mission-operations centers.

This month-long experiment is the first in a series of planned demonstrations to qualify the technology for use on a variety of upcoming space missions. In the next round of testing, a NASA-wide demonstration using new DTN software loaded on board the International Space Station is scheduled to begin next summer.

In the next few years, the Interplanetary Internet could enable many new types of space missions. Complex missions involving multiple landed, mobile and orbiting spacecraft will be far easier to support through the use of the Interplanetary Internet. It also could ensure reliable communications for astronauts on the surface of the moon.

The Deep Impact Networking Experiment is sponsored by the Space Communications and Navigation Office in NASA’s Space Operations Mission Directorate in Washington. NASA’s Science Mission Directorate and Discovery Program in Washington provided experimental access to the Epoxi spacecraft. The Epoxi mission team provided critical support throughout development and operations.
