Las minas. Puede parecer tonto, pero tu las dejas ahí y ellas responderán ante un determinado evento y reaccionarán en consecuiencia. ¿Que es un ejemplo flojo? Los misiles. ¿Alguien los controla? NO, una vez que salen del rail, pueden cumplir su misión de forma totalmente autónoma. Al AMRAAM no es necesario ni siquiera asignarle un objetivo. Puedes dispararlo y el misl buscará un objetivo y lo atacará. Con el tiempo el IFF se implantará en todo y entonces la cosa irá a mas. Ya no hay riesgo de darle a un aliado. La evolución en este aspecto comenzó hace mucho, solo que ahora ha experimentado un gran impulso. A nadie le gusta jugarse el pellejo.
The Swedish Government has decided to participate in the European UCAV-demonstrator program, Neuron.
Saab's participation in the program is thereby secured. “This is a crucial decision for both Saab and Sweden, which secures our participation in one of the most advanced high technology development program in Europe todayâ€, says Saab CEO Á…ke Svensson.
The decision means that Saab, through FMV (the Swedish Defense Material Administration) finances the Swedish participation with MSEK 600 of a total of MSEK 750. At the same time Swedish Government secures that MSEK 600 will be reinvested in the long-term development of the Gripen program.
“Today's decision does not only embrace Swedish Aerospace participation in the advanced Neuron program, but also secures the development of the Saab Gripen fighter programâ€, says Saabs CEO Á…ke Svensson.
Northrop Grumman-Built Global Hawk Surpasses 5,000 Combat Flight Hours
Jan. 4th, 2006
SAN DIEGO, Jan. 3, 2006 -- The U.S. Air Force's RQ-4 Global Hawk unmanned aerial reconnaissance system, built by Northrop Grumman Corporation (NYSE:NOC), recently passed the 5,000 combat flight-hours mark while on a mission supporting the global war on terrorism.
Deployed almost immediately following the attacks of Sept. 11, 2001, Global Hawk unmanned aerial vehicles have been flying nearly continuous combat missions since 2001. The system has now flown 233 missions, 157 of them by a single Global Hawk. Collectively, the family of Global Hawk aircraft has accumulated more than 8,000 total flight hours.
An aircraft program managed by Aeronautical Systems Center's Global Hawk Systems Group includes the first unmanned aerial system to achieve Communication, Navigation, Surveillance/Air Traffic Management compliance.
The RQ4-A Global Hawk achieved CNS/ATM compliance of several systems after being verified by the Electronic Systems Center at Hanscom Air Force Base, Mass. So far, the CNS/ATM approval process has taken about a year and a half to complete. “It was a challenge since no other UAS has done this,”said Bryan Miessler, Global Hawk lead for CNS/ATM approval.
“The requirements are currently written for manned aircraft, which sometimes made them interesting to interpret for an unmanned system.”The current CNS/ATM performance assessment focused on five key areas: Required Navigation Performance; Reduced Vertical Separation Minima; Basic Area Navigation; Mode-S Identification Friend or Foe; 8.33 Kilohertz channel spacing. To date, the Global Hawk has achieved compliance of the RNP-10, RVSM and BRNAV functionalities and will reach Mode-S and 8.33 kHz channel spacing compliance upon successful completion of flight testing, likely in early 2006.
The U.S. Air Force's Global Hawk unmanned aerial vehicle has made its first flight carrying a new sensor that can detect and identify radar and other types of electronic devices from an altitude of 60,000 feet.
Global Hawk and the new sensor, known as the High Band System Production Configuration Unit (HBS PCU), are designed and produced by Northrop Grumman. The HBS PCU is a key subsystem of the Airborne Signals Intelligence Payload (ASIP) sensor which is being developed and is expected to be operationally fielded in 2008. This system will dramatically increase the signals-collection capabilities of the U.S. armed forces. It will be integrated with the Air Force's Distributed Common Ground Stations, which are used to analyze electronic intelligence gathered by various airborne systems.
Northrop Grumman received the first MQ-8B Fire Scout unmanned aerial vehicle (UAV) airframe from its teammate, Schweizer Aircraft Corp.,
on Jan. 3 at Northrop Grumman's new Unmanned Systems Center in Moss Point, Miss., signaling the start of aircraft production. This airframe is the first of 12 Fire Scout vertical take-off and landing UAVs that will be assembled at the Moss Point facility, which is co-located with the Trent Lott International Airport. The U.S. Navy will receive four Fire Scout UAVs and eight will be delivered to the U.S. Army.
Lanzamiento del UCAV europeo
Martes, 17 de enero
El proyecto del avión de combate europeo sin piloto liderado por Francia, y en el que también participan España, Grecia, Italia, Suecia y Suiza, se va a lanzar esta semana, avanzaron hoy fuentes próximas a este programa.
Las fuentes indicaron que al programa de este caza sin piloto, bautizado inicialmente UCAV/Neuron e ideado por el grupo francés Dassault Aviation, podría añadirse próximamente Bélgica.
El proyecto, propuesto en 2003 por la ministra francesa de Defensa, Michele Alliot-Marie, está valorado en unos 400 millones de euros, de los que unos 80 millones corresponden a Francia.
Además de la compañía francesa, están asociados grupos industriales de los otros países implicados: el español EADS CASA, el griego Hellenic Aerospace Industry, el italiano Alenia, el sueco Saab y el suizo Ruag.
Lo que se pretende es desarrollar un avión no pilotado sobre la base de los cazas franceses 'Rafale', y que sea capaz de fijarse un objetivo y de lanzar sobre él un misil.

UK seeks to align Corax stealth prototype with its plans for future military aircraft
17-1-06
Corax bears some resemblance to the cancelled Lockheed Martin/ Boeing RQ-3A DarkStar UAV, with a tail-less configuration, and a long-span unswept wing mounted at the rear of a short body section.
However, there are important differences. The body section is straight-edged and pointed rather than being a half-disc shape. The wing is tapered and mounted relatively further forward, and there are two pitch-control surfaces on each side of the exhaust. This avoids one problem with the DarkStar, which was the limited pitch authority available from the wing trailing-edge surfaces: a factor in the loss of the first DarkStar in April 1996. Compared with DarkStar, which was designed with an emphasis on a low side-on signature - matching its side-looking sensors - Corax is optimised for all-round stealth.
If Corax is the start of a versatile family, it is a step towards the MoD's Strategic Unmanned Air Vehicle (Experiment) - SUAV(E) - which is intended to explore the use of UAVs for deep missions and to pave the way for procurement decisions in 2009-10. As such, it could point the way towards an operational-scale UK UCAV demonstrator.
Reabastecimiento en vuelo automático
Miercoles, 18 de Enero
Mediante un programa conjunto llevado a cabo por el Air Force Institute of Technology y el Test Pilot School de la USAF, se han efectuado una serie de pruebas encaminadas a efectuar el abastecimiento de aviones en vuelo de forma completamente automática.
Para ello se empleó un avión C-12 A (Beech Super King Air 200) que simulaba el cisterna y un Learjet 25 como avión receptor.
Ambos aviones estaban equipados con un sistema GPS modificado y el Lerajet con un sistema de control de vuelo especial para mantener los parámetros de este durante todas las fases de
la maniobra de abastecimiento, que se han llevado a cabo dentro de un “hipódromo”en el que se han mantenido ángulos de alabeo máximos de 30º.
El C-12 “cisterna”estaba equipado con una unidad inercial para medir de forma precisa los desplazamientos en guiñada y alabeo siendo transmitidos de forma automática al Learjet “receptor.â€
Las señales recibidas mediante enlace de datos, alimentan el sistema de control de vuelo modificado de Learjet para efectuar movimientos automáticos de corrección en las superficies de control y en el mando de gases.
Durante los tres últimos vuelos de prueba, el sistema automático del avión receptor se conectó nada más despegar, completando el vuelo de dos horas y media de duración totalmente
en automático y consiguiendo, en vuelo recto y nivelado, mantenerse a 40 cm de la posición ideal programada, es decir dentro de la envolvente de la cesta de repostaje, sin ninguna intervención del piloto.
El éxito de esta prueba constituye un hito histórico en la aviación, pues hasta ahora no se había conseguido una aproximación automática de tal exactitud, lo que abre un enorme potencial en las operaciones de Vehículos Aéreos de Combate No Tripulados (UCAV).
