PERFORMANCE OPTIMIZATION OF A MODIFIED TWIN-ENGINE TURBOPROP COMMUTER PLANE – LET L-410 TURBOLET UVP-E20
Keywords:Airframe, drag polar, engine, fuselage
It has been observed that most low-cost carrier airlines in India (e.g., GoAir, SpiceJet, etc.) do not necessarily cater to remote rural areas and small towns, in terms of flight services and parcel transport. Smaller “bush” airlines operating light regional commuter aircraft have proven to be capable and efficient solutions, as observed in the often otherwise-inaccessible regions of countries such as Canada, Finland, Greenland, Russia and the USA. This only goes on to prove that such aircraft, with the necessary modifications, can quite easily be adapted for service in those out-of-the way, remote and unconnected regions of the Indian Subcontinent. The following report is intended to serve as an example of the performance evaluation of a modified twin-engine light turboprop commuter aircraft, namely, the Let L-410 Turbolet UVP-E20. The modifications so performed are intended to enable the final airframe design to serve as a 15-/16-seater regional commuter aircraft suitable for operation in the rural zones of India. It covers all the areas related to the aircraft’s construction, structure and performance. All the figures/values expressed in this report are extremely close approximations of their existing real-world equivalents, and can therefore be considered as binding on the full-size airframe described here
