PROPCONEL scope of work and measurable objectives
as per call document
Turboprops in the SHP class are currently controlled by hydromechanical components.
The equipment generally allows a maximum of 2 different propeller speeds; they are mechanically connected for pitch control and the oil pressure is provided by a mechanically driven oil pump.
The partner will be responsible for designing, manufacturing and testing advanced components for propeller control: propeller control unit, overspeed governor and oil pump that will be tested at Turbomeca ground test facility.
The propeller control unit will be based on hydromechanical control (flyweights and beta valve), but will integrate electric actuation for speed target and pitch target. It will also allow synchronizing
The overspeed governor will be based on hydromechanical control, with electrical overspeed test and feathering. It will be compatible with the propeller control unit.
The electrical oil pump will be powered with 28VDC, and commanded with a low power input from the engine and propeller computer.
The partner will also be responsible for delivering a dynamic model of each of the components, allowing Turbomeca to design and tune engine control laws. The software used shall be Simulink.

ARGOS scope of work and measurable objectives
as per call document
  Design, manufacturing and test of a constant speed propeller for a 4 cylinder diesel cycle direct drive engine (hub, blades, bearings, cone, governor, counterweights etc.),
Option : Engine dynamic damping and tuning (for SR460) in accordance with the propeller (option of damper integrated in the propeller itself – can be tested on SR305),
 Main Goals & Criteria :
Capable to sustain an increase in baseline engine power by +20% (consistent with WP7.1.1 – i.e. up to about 280 hp) with low propeller maintenance (propeller TBO & intervals between inspections consistent with the engine ones and GA market)
Diameter < 2m, weight < 30 kg, max efficiency over 85% at 2200 rpm
Clockwise (aft looking forward)
Technology capable to be certified
Secondary Goals:
No negative impact on costs: affordable technology consistent with the GA market
No negative impact on performance (thrust, noise, FOD & erosion resistance)
Capability to be inspected and repaired on the field after usual FOD (by grit) and erosion when used on laterite runways
Technology capable of being implemented on feather and reverse versions
