a dire il vero in una delle versioni studiate dagli inglesi come alternativa (più per tirare il prezzo che per convinzione) erano previste le stive ; si doveva riprogettare le ali, spostare il carrello alla radice di queste e installare delle stive al posto dei carrelli sacrificando parte dei serbatoi , che però venivano compensati da altri contenuti nella deriva verticale e nelle ali maggiorate .La diminuzione della resistenza, dovuta all assenza di carichi esterni , aumentava autonomia e velocità

Se è per questo ho visto un immagine di un efa che aveva due bulbi sopra le ali in cui doveva essere presente il serbatoio per il carburante. Questo permetteva di rimpicciolire quello standard e fare spazio ad una stiva per due bombe da 500 libre... Non so che fattibilità abbia una soluzione del genere!

penso proprio che NON fosse un sistema come quello descritto.

probabilmente david ti confondi con i conformal tanks che sono dei serbatoi aerodinamicamente studiati per dare meno attrito possibile e ridurre i consumi .

A che punto è l'aggiornamento degli EFA italiani?

Mi è capitata una cosa alquanto singolare mentre risalivo verso l'emilia in treno: credo di essermi imbattuto negli schemi della "suite elettronica" (diciamo "l'organigramma dei circuiti elettronici") del Typhoon.
Che si trattasse di un aereo mi è parso chiaro sbirciando in un quadratino dello schema che stava visionando il mio vicino in cui spiccava la scritta "landing gear", ma ho drizzato le orecchie quando mi è cascato l'occhio su "Avionic Bus", Weapons Bus", "Attack Bus" ecc ecc.
Poi ascoltando le chiacchiere del mio vicino ho appreso essere un "tizio" (non ho capito quale sia la sua qualifica/ruolo) arruolato nell'AMI e di stanza a Gioia del Colle.
Nella base ci dovrebbero essere solo EFA quindi di quello credo si tratti. Non nascondo che ho sperato (inverosimilmente) che fosse del materiale riguardante l'F-35
Vabbè...sogni ad occhi aperti

[cama81]

ma è possibile portarsi dietro materiale classificato in treno? , mia madre ,professoressa ,non poteva portarsi a casa il registro personale nè gli elaborati degli studenti

Novità per Eurofighter in Giappone, EAU e Arabia Saudita?

Riporto un post del forum inglese www.keypublishing.com che riporta novità tratte dalla rivista Combat Aircraft Monthly, Vol 13, No. 6, June Edition.

Most recent(ish) news:

Eurofighter back on for Japan?

During his official visit to Tokya, UK Priminister David Cameron has renewed the UK's commitment to signing a Defence Co-operation Memorandum with Japan in the near future.

During a meeting with Japanese Prime Minister Yoshihiko Noda, Mr Cameron agreed thet their respective defence ministers would sign the memorandum next time they meet. In parallel, officials will be discussing a range of defence programmes that present industrial opportunities for both the Uk and Japan.

According to the Daily Telegraph, a new package would include British designed Future Combat Ships and additional AW101 Merlin helicopters. If signed, the UK and Japan will collaborate in a number of areas, including mine warfare. In addition, the deal could see Tokya renege on its F-35 buy in favour of the Eurofighter Typhoon to fulfil its F-X fighter requirement. Despite having been rejected in favour of the F-35 in last year's F-X competition announcement, mant see the defence memorandum as a possible route back for the Typhoon. Japan has voiced serious concerns over the F-35 cost and potential delays, and an F-4EJ Kai Phantom replacement cannot be allowed to slip further.

Regarding the UAE:

Elsewhere, British Ministers say the Typhoon still has a chance of winning an order from the United Arab Emirates. The announcement came amid growing rumours that France was close to sealing a $10-billion deal for 60 Dassault Rafales. A previous agreement with Dassault collapsed in 2011 after UAE officials called the proposed terms 'uncompetitive and unworkable'. Gerald Howarth, UK minister for international security, said: 'There is real hope for substantial partnership should the UAE select the Typhoon... it is now a real possibility.'

A few paragraphs from a piece reported by Jon Lake regarding Saudi Typhoons:

Having rejected the Litening pod, the RSAF reportedly considered Lockheed Martin's Sniper pod, before settling on the Thales Damocles pod - already being built in Saudi Arabia by AEC for the RSAF Tornado fleet. Integration work on the Damocles pod is believed to be about to begin at Warton.

Defence News reported that problems in Saudi Arabia with acquiring Paveway IVs were confirmed by Britian's defence attache in Washington, Maj Gen Francis Hedley Robertson 'Buster' Howes. The Paveway IV allows the pilot to select a desired angle of impact and direction of approach for the bomb, as well as a range of fusing options, all selectable by the pilot, in the air. This allows 'effect' to be very precisely tailored, and can allow the weapon to offer very low collateral damage. The American block on supplying Paveway IV to Saudi Arabia, argueably its most important ally in the Gulf region, must have come as agrave setback to the RSAF.

The RSAF is now understood to be looking at acquiring the Sagem AASM (Armement Air-Sol Modulaire, air-to-surface modular weapon) Hammer in place of the Paveway IV, and is looking to this on both the Tornado and the Typhoon.

The Saudi plans to use the Damocles and AASM on the Typhoon demonstrate a hitherto unexpected capability for integrating new weapons and systems on the aircraft flexibly and in a rapid timescale, and seem to show that hitherto slow pace of weapon integration has been imposed by funding constraints and not by any technical difficulty.

It is believed that BAE Systems is offering further air-to-ground weapons options and integrations to the RSAF (perhaps including an early integration of the Storm Shadow cruise missile), and in shorter timescales, supporting the RSAF's aspiration to keep the aircraft at the core of its future fleet plans. These could see the Kingdom ordering further Typhoons.

This could prove to be of pivotal importance to a number of potential Typhoon customers, including the United Arab Emirates , who could perhaps see the Saudi example as evidence that a similar stand-alone integration of their Black Shaheen stand-off missile on the Typhoon could be achieved before any NETMA clearance of a Taurus/Storm Shadow integration.

In un articolo in cui si parla della prossima consegna di un esemplare del radar AESA "Raven" di Selex destinato allo sviluppo della versione evoluta del "Gripen", si fa anche il punto sull'andamento del programma relativo al "Captor-E" che dovrebbe/potrebbe equipaggiare le future versioni del "Typhoon" ....

Meanwhile, work on the Euroradar Captor-E AESA for the Eurofighter Typhoon is also proceeding, with EADS company Cassidian acting as design authority for the new array.

"We are cracking on, with hardware coming together," Mason says. The first test radar should be delivered early in the second quarter of 2013, and flown by Eurofighter partner company BAE Systems on a Typhoon before the end of that year.

The design retains an upgraded processor and receiver from the mechanically-scanned Captor-M, but adds a new array and an electrically-steered repositioner which will increase the sensor's field of regard by +/-100˚.

"The gain in performance is well worth any minor degradation in mean-time between failure," Mason says. The AESA will deliver enhanced detection performance in air-to-air and air-to-ground modes, plus a synthetic aperture radar mapping function.

Mason says discussions with the four core Eurofighter partner nations are continuing, and believes that "those that have money will join the [AESA] programme in the near future". A production contract could come by mid-2013, with deliveries to commence from around 2015.

The Captor-E will be available as an option for Tranche 3A aircraft to be built for Germany, Italy, Spain and the UK, and as a retrofit option for their Tranche 2 aircraft, along with those of Saudi Arabia. The enhancement is also being offered to other potential export customers for the Typhoon, including Malaysia and the United Arab Emirates.
