The BD-5 is a high performance single-place, low-wing, pusher-configuration sport plane. Design features include all-metal construction, mechanical retractable landing gear among the industry finest, detachable wings, and wrist action side stick control as in modern day fighter aircraft. Originally developed in the early 1970's the aircraft was designed to day VFR requirements for use in sport and recreational flying, including limited aerobatic capability.

Originally it was powered by a 40-hp Hirth snowmobile engine and was fitted with a wingspan of 14 feet. More recently the wingspan was stretched to 17 feet and the more powerful Xenoah three-cylinder two-stroke engine was installed. The pilot is seated under a transport canopy forward of the engine in a heated cockpit. The landing gear is fully retractable, and the entire fuselage/wing structure is constructed of light alloy materials.

Oshkosh 1973 was the year the BD.5 appeared and it provided a spectacular show in the hands of Les Bervan, Bede's test pilot. It performed both in long and short winged versions and with a retracting gear. The jet powered BD-5J also made its first public appearance.

BD-5J

The BD-5J was powered by a 100-kg (202-lb) thrust Microturbo jet engine, spans 5.18 m (17 ft), and is fully aerobatic.

After the collapse of Bede, the BD-5 became available as modified conversions such as the Alturair BD-5.

BD-Micro Technologies, in late 1995, offered enhanced BD-5 kits. Enhanced BD-5 Kits are designed to be assembled in the shortest time with the least hassle.

Components (Wings, Flaps, Ailerons, Vertical Stabilizer, Horizontal Stabilator, Rudder, Fuselage, Landing Gear, and Nose Gear Box) come predrilled on factory jigs. Machined, welded, and difficult to form parts are supplied.

The .032" thickness wing skins with modified leading edge improves stall and slow flight control.

Flightline BD-5T Turboprop


The BD-5T Turboprop kit features everything except paint & avionics. With the standard components (Wings, Flaps, Ailerons, Vertical Stabilizer, Horizontal Stabilizers, Rudder, Fuselage and Landing Gear) pre-drilled on factory jigs, and machined, welded, and difficult to form parts are supplied.


The BD-5T features a fuselage superstretch of 13.4 in and supplementary wingspar system, detachable wings and control system (20 minutes for assembly or removal), and detachable horizontal stabilizer.


Power is from a Quantum H-95 turboshaft engine and Quantum III Propeller. The propeller is developed specifically for turbine engines, weighs 11 lbs including hub and 3 blades. The Quantum turboprop powerplant system (engine & propeller) was designed for the BD-5T. It is a constant speed, torque variable turboshaft engine based on Solar T-62 series components.

 

In 1992, Ed ("Skeeter") and Richard Karnes started BD Micro Technologies Inc. (BMT), beginning a long journey to update the BD-5 with modern technology while using current building techniques. After many years of research and development, BMT has successfully incorporated many improved design features in an aircraft lineup called the "Flight Line Series" or "FLS" kits.

FLS safety advances include improved stall characteristics, increased pitch stability, reduced airframe fatigue, and modern technology integration focused on increasing systems reliability while reducing pilot workload. Lewis, who formed Lewis & Clark Performance LLC, collaborated with BMT to build the first complete FLS Microjet.


Flightline Series BD-5B kit features a complete airframe package - less engine, engine systems, paint & avionics. With the standard Wings, Flaps, Ailerons, Vertical Stabilizer, Horizontal Stabilizers, Rudder, Fuselage and Landing Gear) pre-drilled on factory jigs, and machined, welded, and difficult to form parts supplied, construction time is around 900-1000 hours.
Assembled quickly and easily with common skills.
Engines can be in the Hirth 2706, Xenoah range.
The Flightline Series BD-5J Microjet airframe kit features a complete airframe package requiring 600 to 800 hour construction time. Components (Wings, Flaps, Ailerons, Vertical Stabilizer, Horizontal Stabilizers, Rudder, Fuselage and Landing Gear) are pre-drilled on factory jigs anf the fuselage preassembled to "On the Gear" stage. Machined, welded, and difficult to form parts are supplied. Parts are manufactured to aircraft industry standards. The Flightline Series BD-5J Microjet has FLS turbine structural airframe enhancements and a fuselage stretch, 5.2 in. (optional 13.5 in superstretch). The BD-5J has fuel quick disconnects, NACA jet engine intake scoops, Super Spar (supplementary wing spar system), Microjet disc brakes, a Hartwell canopy latch system, and a 5-point safety harness system.
With adjustable seating and side stick control, the retractable landing gear cycles in one second.
Detachable wings and control system takes 20 minutes for assembly or removal. The horizontal stabilizer is also
detachable.
The engine is also equipped with an attenuator designed to cut thrust.

Alturair produced a modification of the standard Bede BD-5 to accept an alternative engine.

William 'Wild Bill' Brooks Cornville (Arizona) BD-5J Trijet

 

Bill Brooks flew a BD-5B with a Solar T62, then modified it with 3 HJFS-100 55 Kp units (pod 2 and 1 in the fuselage) and a canard in the front. It is more than probable that he never flew in this configuration.

It was bought by Dave Dearing in 2004 who changed it to standard 5J (the wing is still that of a 5B).
Engine side, Dave acquired a Christmas Penny NPT301.

 

BD-5-Glu
EMG G8-2-130 powered BD-5

 

Leolan McRorey was the first owner of BD-5 to have equipped it with two Gluhareff EMG G8-2-130 pulse jets.
These jets are mounted on a steel rod to each side of the rear fuselage. This configuration was chosen to create a separation between the motors and to avoid the propagation of sound waves.
The small size of the BD-5 managed to board 50 liters of propane in two tanks, a 20 and 30 liter.
Instead of installing a dual throttle, he decided to change the position of the two engines, close to the fuselage.
