Some Small Turbine Photos

A turbofan engine should allow full VTOL capability in this 1/6 scale model of the Harrier Jump Jet.

This A-10 model has a wingspan of 10 ft and weighs 55 lb. It is powered by two Wren turbojet engines producing 14 lb of thrust apiece.

JetCat's engine monitoring software can be used for real-time monitoring or to view recorded flight data.

The JetCat 120 engine is 4.4" in diameter, weighs 3.1 lb, and produces 26.5 lb of thrust. The price with electronics, fuel pump, and auto starting system is 3,695.

The JetCat HP5 is a turbine engine with the gearbox and accessories necessary to power model helicopters. It's list price is $4,395.

This 2.25" turbojet engine was designed and built by Ewald Schuster. It weighs 6.5 ounces, produces 4 lb of thrust, and operates at up to 220,000 rpm.

This turbofan engine is under development by Ewald Schuster. It will produce 45 lb of thrust for a 1/6 scale Harrier jet model.

The model was designed using AutoCAD and the wooden framework was cut with a laser cutter. Balsa sheeting covers the frame. This photo was taken after only 11 days of contruction.

The wing for the BVM Super Bobcat model uses balsa ribs across graphite composite spars, covered with sheeting. This wing handles 200+ mph stresses in an aircraft with a 65" wingspan. BVM also sells version of the Bobcat with graphite composite in place of balsa.
