The need to monitor the territory, as can be seen from Regional, National and International requests, is strong and growing. The development of technologies for environmental monitoring and regional safety represents an important aspect for the management and control system. Fixed or rotary-wing aircraft are currently used in this role for monitoring coastlines and borders, traffic surveillance, fire prevention and photographic surveying. Today the operation of these aircraft are characterized by high costs. A better solution could be obtained by exploiting a new class of vehicles: small-sized helicopters defined as VLR (Very Light Rotorcraft) characterized by low design, production, maintenance and operative costs. Crucial for the development of this new class of aircraft is the selection of an innovative engine system that will ensure the aircraft to be A-class certified. In base to the EASA CS-27 regulation, this feature can allow the helicopter to operate for aerial work and to fly over urban centers and bodies of water.
The solution analyzed is represented by the piston engine TEPS (Twin Engine Pack System). Despite coming as a “single unit”, the TEPS is in fact the integration of two engines capable of operating in synch. The added value is represented by the capability to work individually and independently, despite coexisting in a single engine body, in case of emergency. Scope of the project is the design this new class of rotorcraft for territorial and environmental monitoring missions. Up to now the aerial photogrammetry has always been carried out by airplane and satellite. This project aims to deduce the technical requirements of an environmental photogrammetric mission as it is done today and to apply and adjust these parameters to an innovative technology that would allow to implement environmental missions also by helicopter. The team also defined alternative mission scenarios and identified viable design configurations, together with the study and the integration of the TEPS engine, sub-systems and an innovative FMS (Flight Management System).

The revolutionary piston twin pack engine contains two engines in a single unit, making it possible to reach noticeable performances while keeping the flight safe. The helicopter can overfly cities and densely inhabited areas without the limitations of a single engine machine. The simple construction and aerodynamic choices, together with the compact size make it a reliable and cost-effective vehicle.
