The Hongdu JL-8 (or Nanchang JL-8), also known as the K-8 Karakorum, is a two-seat intermediate jet trainer and light attack aircraft built in joint-cooperation between the People's Republic of China (China Nanchang Aircraft Manufacturing Corporation) and Pakistan (Pakistan Aeronautical Complex). The contractor for this plane is the Hongdu Aviation Industry Corporation. Export versions are designated K-8 Karakorum, after the mountain range that separates China and Pakistan.
History
The K-8 trainer was built through joint cooperation between the governments of Pakistan and the People's Republic of China. Initially, the aircraft was to feature many United States parts, but due to political developments at the end of the 1980s, this plan was scrapped. The first prototype was built in 1989, with the first flight taking place on 21 November 1990.
The Pakistan Air Force (PAF) first received fourteen K-8 trainers in 1994, after which it decided to order 75 more to replace its fleet of Cessna T-37 Tweet trainers. The People's Liberation Army Air Force (PLAAF) received its first six K-8 trainers in 1998. Later upgrades to the Chinese model included an indigenously-manufactured Chinese engine. The PLAAF is anticipated to continue adding the trainer to its fleet in order to replace older trainers that are now obsolete, such as the Chengdu JJ-5.
Other nations have shown interest in the trainer and it now also serves in the air forces of Egypt, Sri Lanka and Zimbabwe. While the type primarily serves as a trainer, it can also be used in the close air support or even air combat role when appropriately armed.
The K-8 Karakorum-8 Basic Common Advanced Jet Trainer is co-developed by the Aircraft Manufacturing Factory (AMF), Pakistan Aeronautical Complex; and China National Aero-Technology Import & Export Corporation (CATIC). The Chinese designer of the aircraft was Mr. Shi Ping (石屏) and the chief test pilot was Mr. Yang Yao (杨耀).
The latest development in the K-8 family is the K-8P version, which currently is operated by the PAF. The K-8P has an advanced avionics package of integrated head-up displays (HUDs) and multi-function displays (MFDs), also equipped with MFD-integrated GPS and ILS/TACAN systems.
In 2008 Venezuela announced the purchase of 18 K-8 aircraft. Currently the K-8 is being marketed by China to the air forces of the Philippines; and to Indonesia, as a replacement for Indonesia's BAE Hawk jet trainers.[2] In 2009, the Bolivian government approved a deal to purchase 6 K-8P aircraft for use in anti-drug operations.[3]
Design
The K-8 has a multi-role capability for training and, with little modification, can also be used for airfield defense. The aircraft is supposed to be as cost-effective as possible, with a short turn-around time and low maintenance requirements. Export variants of the K-8 (K-8E, K-8P) and domestic Chinese variants (JL-8) have differing powerplants and avionics configuration.
Airframe and flight control system
A low-wing monoplane design primarily constructed of aluminum alloys, the K-8 airframe structure is designed for an 8,000 flight hour service life.
The landing gear is of tricycle configuration, with hydraulically-operated wheel brakes and nose-wheel steering.
The flight control system operates a set of conventional flight control surfaces with a rigid push-rod transmission system, which itself is electrically- or hydraulically-operated. The aileron control system, of irreversible servo-control type, is composed of a hydraulic booster, an artificial-feel device, a feel trim actuator and a rigid push-rod transmission mechanism. The elevator and rudder control systems are of reversible push-rod type.
Cockpit and avionics
The cockpit arrangement is designed to be as close to that of a combat aircraft as possible. A transparent plastic canopy covering both cockpits, which are arranged in a tandem seating position, is supposed to give a good all-round field of view.
A Rockwell Collins Electronic Flight Instrument System (EFIS) is fitted, with multi-function displays (MFDs) in the front and rear cockpits showing information to the pilots. The emergency cockpit escape system is made up of two Martin-Baker MK-10L rocket-assisted ejection seats which are zero-zero capable, meaning they can be used safely at zero altitude and zero speed.
Ultra high frequency (UHF) and very high frequency (VHF) radio communication systems are present, along with a Tactical Air Navigation (TACAN) and automatic direction finder (ADF). An instrument landing system (ILS) is also available. These systems can be tailored to meet the requirements of the customer.
A strap-on Environmental control system (ECS) from AlliedSignal provides air conditioning to the cockpit. It is capable of operating when the aircraft is on the ground, under ambient temperatures of -40 to +52 °C, as well as in the air.
Propulsion and fuel system
The Chinese domestic variant of the K-8 (JL-8) was originally powered by the Ukrainian Ivchenko-Progress AI-25TLK turbofan jet engine, but this has been replaced by the WS-11, the Chinese-manufactured version of the AI-25TLK. Export variants (K-8P, K-8E) can be fitted with the more powerful and efficient Honeywell TFE731-2A-2A modular turbofan, which has digital electronic engine control (DEEC), if the US government approves sale of the engine to the customer.
A hydro-mechanical fuel control system delivers fuel to the engine. The aircraft's fuel system consists of the fuel tanks and the fuel supply/transfer, vent/pressurization, fuel quantity measuring/indicating, fuel refueling and fuel drain subsystems. The total fuel is contained in two fuselage bladder-type rubber tanks and a wing integral tank of 1720 lb. The capacity of each drop tank is 250 litres.
Operational history
The K-8 took part in its first aerial display to the Pakistani public on 6 April 2010 by the Sherdils (Lion Hearts) aerobatics team of the Pakistan Air Force. K-8 replaced the team's previous T-37 Tweet aircraft.[4][5]
