PJ-II "Dreamer- Ducted fan Jet "Replica"

"The "PJ-II "Dreamer" is two seater "Ducted Fan" fighter Jet "replica" kit-build aircraft.

PJ-II "Dreamer"

"Replica" is in inverted commas because it was never intended to be design as exact copy of any current "Jet Fighter". And with little "cosmetics" changes , it's can be made looks like any countries twin engine jet fighter plane. It has similarities to the Russian Mig-29, Su-27, or USA F-15.

The aircraft is made of composite constriction with all the parts made in the "moulds". Standard fibreglass and resin (Carbon fibre can be used, as a customer request) is used throughout, being of aerospace quality sourced from Germany. Skins with ribs and bulkheads are utilised in a fairly traditional composite build up for sophisticated high performance experimental aircraft.

PJ-II "Dreamer" being Built

PJ-II "Dreamer" design around LS6 GM V-8 400hp automotive piston engine which has been converted for aircraft use. Because this is automotive engine, automotive premium or aviation LL100 fuel can be used The "Ducted Fan" propulsion system makes this aircraft look and fly like a jet airplane. It's no P-factor and torque to deal with as experienced in standard propeller driven airplanes.

Long-time efforts of co-thinkers are embodied in this model of aircraft, which is unrivalled throughout the world, as it is the first-ever manufactured operational “replica” of a two-seat jet fighter aircraft with Ducted Fan propulsion system.

Certificate of Airworthiness of the Federal Air Transport Agency of the Russian Federation, number 2082164591, was received on February 9, 2016.

Demonstration flights of PJ-II at the exhibition Sun-n-Fun 2016 in Lakeland, Fl. USA, April 2016, arouse much interest.

This strengthened confidence in the demand for this model in the world market. During the air show and in the following few months, the interest was confirmed by the announced intentions of more than 50 pilots, who wished to purchase PJ II kit-build aircraft.

Being conscious of the importance of taking on commitments to the timing of orders, and the need to retrofit the retractable landing gear system, which requires a certain time, a slight pause was taken by Garuda Aircraft.

The company has reached an understanding, that manufacturing and developing will allowed producing only 12 kits in 2017, with the increase in their number in 2018 and beyond.

LS series of engines have the ability to run at high rpm for extended periods of time. In 2008 the LS6 was the latest and greatest engines in sport cars and race cars industry. Supplanted by the bigger, “badder” LS7 GM "crate" motor, 450 reliable horsepower is readily available. The LS6 and LS7 engines have same external dimensions and mounting points, no need to change anything, to replace LS6 to LS7.

LS7 GM

Gearbox designed to accommodate both engines. LS series engines has a custom adapter plate to accommodate an Airflow Performance Fuel injection unit similar to the ones used on certified aircraft piston engines. Don Rivera (APF) came up with the design that bolts a FM300 control unit right on to the stock intake manifold. No computer involved, it has traditional throttle and mixture controls. For ignition, MSD Basic timing unit specifically designed to convert LS engines from factory computerised fuel and ignition systems to race car style motors. Other engine mods are few and simple. LS engines are the only ones, that don't need to be stripped down completely and rebuild to accommodate aircraft use. The gearbox driven through the dampened fly-wheel has an output drive flange on either side of the fuselage-mounted engine that just protrudes into air intakes ducts.

Cockpit layout

A shafts with universal joints on each end drives a five bladed fans that is rigidly supported in the duct. Instead of the traditional PSRU that reduces the prop speed relative to crank speed, this one speeds the fans to 7000 RPM at take-off.
