Taiwan Province IDF fighter upgrade plan.

Since 200 1, Han Xiang has been carrying out a three-stage F-CK- 1A/B fighter improvement plan called "Ascension Plan", with a total expenditure of NT$ 7 billion, which is implemented by Chinese Academy of Sciences and Han Xiang Company. The first stage of the plan aims to increase the bomb load of F-CK- 1A/B fighters from the original two Tian Jian -2A air-to-air missiles to four, and integrate the new Tian Jian -2A anti-radiation missile and Wan Jian's new cluster bomb. The second phase plan includes upgrading F-CK- 1A/B fighter mission computer, electronic countermeasure equipment (ECCM), electronic warfare system, advanced identification of friend or foe (AIFF) system, and improving terrain tracking and radar system. The third phase of the plan will include ground and air flight tests. Once it passes the air force evaluation, the improved F-CK- 1A/B fighter is scheduled to enter service in 20 10. Xiangsheng plan mainly aims at finding substitutes for discontinued parts and upgrading avionics system and CFT. The avionics system is expected to be upgraded, including replacing BAE's 32-bit flight control computer, replacing radar components, adding electronic countermeasures, electronic warfare system, advanced friend-or-foe identification system, terrain following mode and other functions, upgrading the mission computer, and replacing the cockpit display with three full-color multifunctional displays. The airframe structure is strengthened by installing two CFTs with a volume of about 7,765,438+0 liters. At the same time, according to the increased weight of CFTs, the engine thrust is slightly increased, the tail engine profile is raised, the belly semi-buried pylon is cancelled, and the weapon load is increased (the number of Tian Jian II medium-range air-to-air missiles is increased from 2 to 4, which can carry Tian Jian 2A anti-radiation missiles), thus enhancing the short-range take-off and landing capability. The first eagle made its first flight on June 4, 2006, and was exhibited in public in a very low-key manner the day before June 9, 2006. This exhibition is only open to Han Xiang employees and their families. The F-CK- 1C/D numbers are 10005 and 10006. The exterior painting was designed by Mr. Xu, and the test pilots were all instructors Zhu Taihua. Xiangsheng project

In the technical development stage, it is estimated that two technical verification machines will be produced, and the factory numbers are single seat 10005 and double seat 10006 respectively. Among them, the airframe structure numbered 10005 is still in the old configuration, and only the avionics system is upgraded and verified; Airframe number 10006, delivered in 2007, with complete configuration, will include all airframe and avionics improvement projects. The aircraft 10006 was officially released on March 27th, 2007, and was named Goshawk by Chen Shui-bian. There are media reports that this is in line with "going to Chiang Kai-shek", and it is controversial to rename the "Guo Jing" fighter as "Eagle". In fact, "Eagle" can only be used to refer to the new fighter after the completion of the Xiangsheng project, and it is a new name for the new fighter. The original "Guo Jing" fighter is still a Guo Jing fighter, which is different from the "Eagle" fighter and has not been renamed.

● (IDF) F-CK- 1 A/B National Fighter.

● (IDF) F-CK- 1 C/D Eagle Fighter

Update the cockpit interface of elevator.

Install a new integrated color display system (ICDS). The main components include the following:

● Scanning/vector head-up display (raster /Storke HUD).

● Three large color liquid crystal multifunction displays (CMFD)

● Color cockpit photography system (CCTVS)

● New integrated head-up control/input panel (UFCP)

● The original six groups of engine monitoring instruments under the right panel are updated to electronic engine display system (EEDS).

● Standby electronic flight instrument (STBY EFIS Company)

The avionics system of Xiangsheng Aircraft adopts 32-bit flight control computer of BAE Systems Company, which replaces the original standard flight control computer of 16-bit 1750 of Lear Astronics Company, and a brand-new FBW flight control mode (such as terrain tracking) is built into the computer to provide stronger processing capability. Albert Lin, project manager of BAE F-CK- 1C/D, said that this 32-bit computer based on PowerPC processor is the fourth generation flight control computer adopted by F-CK- 1C/D, replacing the 16-bit 1750 standard computer on A/B model. The A/B fly-by-wire control system is a three-redundancy digital plus three-redundancy analog backup system, while the C/D model does not need the original analog backup system. Lin said that the analog backup system provided good flight control quality for the F-CK- 1A/B aircraft: "Flight officials initially preferred analog systems to digital systems". Lin also said that the development of C/D flight control system and control law is the responsibility, and BAE Systems only provides computers-six flight control computers have been provided for two Xiangsheng prototypes.

Core avionics system update

● Introduce a set of color display processors.

● Expand the bus architecture to three sets of 1553B military standard interfaces (there is room for upgrading to four sets of 1553B military standard interfaces).

● Update flight procedures.

Communication/Navigation/Friend or Foe Identification System Update (CNI)

● Replace with a new inertial navigation system (GPS/INS).

● Replace two sets of new UHF/VHF radios (ARC-2 10).

●APX- 1 13(V)AIFF advanced friend or foe identification system.

Update of GD-53 launch control radar

GD-53' s 5-piece LRU was changed into 3-piece LRU architecture, and all the old 3-piece LRU such as radar target processor, radar data computer and control/power supply were replaced with 1 new radar data processor (RDPs).

New working mode of GD-53 elevator launch control radar;

● Combined radar mode (CRM)

● Groove area indicator for tracking target.

● Automatic scanning adjustment (TWS) in scanning synchronous tracking mode.

Conformal fuel tank CFT

The two CFTs installed on the Eagle aircraft are located at the rear, covering almost the entire rear of the aircraft. The total oil load of these two CFTs is 65,438+200 lb (545 kg, only 40% of the F-65,438+06 Block 50/52 CFT), which makes the range of elevators increase by 20% on average. In the future, it will be decided whether to increase the fuel load of two CFTs according to the engine thrust and customer demand. The weapon system strengthening plan of F-CK- 1 fighter includes a variety of weapons under development, such as Qingyun oil-gas bomb and Wan Jian bomb, in order to increase the ground strike capability of F-CK- 1 except air superiority tasks.

Qingyun oil and gas bomb

A kind of oil-gas bomb developed by Chinese Academy of Sciences can kill a large area of personnel and equipment, and give a devastating blow to large troops or material assembly areas.
