The Regional Transport Aircraft (RTA) project of Hindustan Aeronautics Limited (HAL) and National Aerospace Laboratories (NAL) known as Indian Regional Jet (IRJ) has entered in the Testing phase.
A wind-tunnel model of Regional Transport Aircraft 70 (RTA-70) undergoing test at National Wind Tunnel Facility IIT Kanpur. The NWTF is a closed-return, continuous, atmospheric wind tunnel equipped with several auxiliary systems for different testing needs.
The test section of NWTF is 2.25m high, 3m wide and 8.75m long and is split into two parts; an upstream (5.75m) and a downstream (3m) part. Air speed up-to 80m/s produced by a single-stage 12-bladed axial-flow fan powered by a 1000kW motor.
National Aerospace Laboratories (NAL) jointly designed and developed a 70-seater civil regional aircraft. The RTA-70 is meant to fly short-haul routes and compete with planes of French-Italian aircraft maker Avions de Transport Régional (ATR), a leading exporter of turbo-prop aircraft in the region.
NAL had held discussions with Pratt and Whitney (Canada) and General Electric (U.S.) for an engine. The aircraft is claimed to offer 25% lower acquisition costs, 25% lower operating costs and 50% lower maintenance costs than existing turboprop aircraft.
The 70-seat aircraft will have a range of 1,350 nm (2,500 km), and require a take-off field length and landing field length of 900m (2,950 ft). The aircraft would have a length of 28.6m and a wing-span of 29.4m. The aircraft would have a service ceiling of 30,000 ft, a cruising speed of 300kt.
NAL is considering a composite airframe. The aircraft will be powered by two "next-generation turboprop engine". It would have an indigenous fly-by-wire control system, open distributed modular avionics, automatic dependence surveillance - broadcast navigation capabilities, and advanced displays.
