SP-110 TS ROS Two Stroke Engine (exhaust at the top)

The SP-110 TS ROS (exhaust at the top) is the smallest two-stroke engine with twin spark for a wide range of applications with UAS.

This engine is a common engine system on UAS programs from 45-65kg MTOW. With the same core architecture as other dual cylinder engines in our portfolio, the SP-110 TS ROS with 110 ccm offers power density and reliability in all operational scenarios.

The SP-110 is equipped with dual spark plugs per cylinder, the crankcase is CNC machined and the cylinder is casted aluminium. The ROS feature enables greater operational diversity, to include a starter generator which can be configured into a hybrid or power generation capability.

The following additional configurations can be offered:

  • No rear output shaft
  • Rear output shaft
  • Generator and Controller
  • Starter Generator and Controller
