1. 1. Maritime Patrol Aircraft
2. 2. Introduction The CASA/IPTN CN-235 is a medium-range twin-engined transport plane that was jointly developed by CASA of Spain and Indonesian manufacturer IPTN, as a regional airliner and military transport. The maritime patrol variant is in service with: Spain, Ireland and Turkey (manufactured by EADS CASA) and Indonesia, Brunei and UAE (manufactured by Dirgantara). Its primary military roles include maritime patrol, surveillance, and air transport. Its largest user is Turkey which has 50 aircraft.
3. 3. Variants CN-235-10: Initial production version (15 built by each company), with GE CT7-7A engines. CN-235-100/110: Generally as series 10, but with GE CT7-9C engines in new composites nacelles; replaced Series 10 in 1988 from 31st production aircraft. Series 100 is Spanish-built, series 110 Indonesian-built, with improved electrical, warning and environmental systems. CN-235-200/220: Structural reinforcements to cater for higher operating weights, aerodynamic improvements to wing leading-edges and rudder, reduced field length requirements and much- increased range with maximum payload. Series 200 is Spanish-built, Series 220 Indonesian-built. CN-235-300: CASA Modification of 200/220 series, with the Honeywell International Corp. avionics suite. Other features include improved pressurization and provision for optional twin-nose wheel installation. CN-235 MPA: Maritime patrol version with 6 hardpoints to carry AM-39 Exocet-Missiles or Mk.46- Torpedos.
4. 4. Design Two General Electric CT&-9C3 turboprop engines each developing 1,305kW, are wing-mounted in composite nacelles. The engines produce 1,394kW with automatic power reserve. The engines drive Hamilton Sundstrand 14RF-21 four-bladed, constant speed, full feathering, reverse pitch propellers, diameter 3.35m. The propellers are of glass fibre construction with a metal spar and urethane foam core. The aircraft is equipped with a Trimble TNL7900 Omega global positioning system and a Northrop Grumman (formerly Litton) LN92 ring laser gyroscope inertial navigation system.
