A proliferation of large wind farms in recent years has posed a new challenge to both air traffic control and the renewable energy industry. The rotating blades of wind turbines can appear as false aircraft returns on air traffic and other radars. This clutter can lead to radars becoming de-sensitized in the area of the wind farms, resulting in genuine aircraft tracks being all too easily lost. This phenomenon has already prevented or delayed the establishment of new wind farms due to objections from aviation authorities.
Diamond Aircraft is showing a maritime-surveillance version of the popular DA42 MPP Guardian, equipped with the company’s own radar, in the static park here at the Farnborough Airshow. Founder of the Austrian company, Christian Dries, told AIN that Diamond developed the spinning AESA radar in the past 12 months, because conventional radar houses could offer only a two-year lead time. Diamond’s radar weighs less than 20 kg (44 pounds), offers a range of 120 km (75 miles), and also includes AIS, the maritime equivalent of IFF. Endurance of the aircraft is 12 hours.
Monday’s announcement by Prime Minister David Cameron that the RAF’s Raytheon Sentinel R1 fleet will be extended in service until at least 2018 has breathed new life into the program, and sparked real interest in further development.
One of the key features that could be added is a greater maritime capability. While the RAF is quick to stress that a maritime-capable Sentinel is not a maritime patroller, it could be used as a gap-filler in certain scenarios, and has considerable applications in littoral operations, such as amphibious landings or humanitarian missions.
This year, L-3 Aviation (Chalet A10-15) should generate more than $500 million in sales, according to Ralph DeMarco, v-p of marketing and sales.
The Eurofighter Typhoon IPA5 has arrived at Farnborough carrying precious cargo. Beneath the nose radome is the first flight- test example of the Euroradar Captor-E WFoR (wide field of regard) electronically-scanned radar. The sensor was installed only recently and, after a few shakedown flights, the aircraft was ferried south from BAE Systems’ airfield at Warton, Lancashire, for the show.
On a flying visit to the Farnborough Airshow yesterday, UK Prime Minister David Cameron announced a major boost to the UK’s defense budget by pledging £1.1 billion to a package that both extends current capabilities and introduces new ones. Cameron specifically mentioned Raytheon/Bombardier Sentinel and the Beechcraft King Air-based Shadow airplanes, which were due to be withdrawn next year following the UK withdrawal from Afghanistan, but which have proved of such use that they are to be retained for at least three more years.
Ukrainian defense electronics group Aerotechnica (Hall 2 Stand C28b) has been at the forefront of the urgent effort to modernize the country’s air defenses in response to the military standoff with Russian-backed separatists. It specializes in replacing dated radar hardware, such as vacuum-tube modules and traveling wave-guide tubes with solid-state components. The company has successfully performed this upgrade with numerous radar sets, most notably the P-18.
At the recent ILA Berlin Airshow, Airbus Defence & Space reported progress with the passive radar [alternatively, passive coherent location (PCL)] system that predecessor company Cassidian had been developing since 2006. Frank Bernhardt, project manager, said that the company has “worked closely” with two armed forces on tests of the system. One of them is Germany.
European companies, especially in the East, are continuing to refine passive ground-based technologies with the potential to detect stealth aircraft. The best known of these is the detection and correlation of emissions from aircraft–such as from radars, radar altimeters and other navigation devices–using ESM/ELINT techniques, sometimes known as passive emitter tracking (PET).
NBAA released a new publication, “NBAA Aircraft Transactions Guide,” to assist those considering buying or selling a business airplane. Developed by the NBAA Tax Committee, the guide provides background on the most relevant FAA and DOT regulations, federal and state tax issues and aircraft ownership structures. It also maps the various steps of the aircraft transaction process, from the letter of intent to the closing.
