Beijing tech show highlights advances in Chinese fighter sensors

A-Star's EOTS-86 appears to be similar to the Electro-Optical Targeting System (EOTS) that equips the Lockheed Martin F-35.

China's Jiangsu A-Star Aviation Industries Company (A-Star) used the first Beijing exhibition promoting "civil-military integration" to reveal new combat aircraft electro-optical systems, some of which may be slated for the country's fifth-generation fighters.
A-Star's booth featured images of a Shenyang Aircraft Corporation J-31 fifth-generation export fighter to highlight two electro-optical systems, although it is not clear that A-Star's systems will equip future developments of this fighter, revealed as the FC-31 at the November 2014 Zhuhai Air Show.

A-Star's EORD-31 appears to be a conventional infrared search and tracking (IRST) system but with a faceted sensor dome;

The EOTS-89 resembles the Electro-Optical Targeting System (EOTS) of the Lockheed Martin F-35, which combines Forward Looking Infrared and Infrared Search and Track (IRST) capabilities. The similarity includes the use of two tracking mirrors and a flat-facetted optical window, with bottom fuselage placement just aft the radar radome. Such a system was so placed on the large mock-up of the FC-31 seen in November 2014.

The AUEODS system by A-Star uses two wingtip mounted pods that combine a domed IRST with a conventional targeting pod.

Shown placed on the front starboard side of the J-31 canopy, A-Star's EORD-31 serves as an IRST, similar to the OLS-27 series used by the Russian Sukhoi Su-27 fighter. However, instead of a spherical dome cover, the EORD-31 is flat and facetted. Chinese press reports claimed the system may be able to detect a Lockheed Martin F-22A at 110 km and a Boeing B-2 at 150 km.
Also on display was an image of A-Star's "AUEODS" system, which uses TX-S55 and TX-S56 pods which combine a conventional targeting pod with an over or under-mounted domed IRST. These two pods were shown on a Su-27 on the wingtip position taken by SORBITSYA electronic warfare pods.

image from A-Star indicated that its new F-80 medium range air-to-air missile
may have a ground attack capability. (Via Top81 web page)
Chinese press reports claimed it can detect targets out to 200 km, or 70 km for the F-22A and 120 km for the B-2. The reports also claim it can detect a Tomahawk cruise missile out to 18 km.
A-Star used the 2014 Zhuhai Air Show to reveal its F-80 medium-range air-to-air missile with a unique five flat facet for its infrared/imaging seeker. While its range has not yet been disclosed, A-Star used the recent Beijing exhibition to indicate it has a ground-attack capability.
A-Star's range of products also includes the five-seat German Extra EA-400 turboprop powered light aircraft, obtaining co-production rights in 2013.
