Founded in 1999, Trek Aerospace, Inc. is a small engineering company based in Folsom, California, USA. The company has designed and made multiple vertical takeoff and landing (VTOL) aircraft including its exoskeleton jetpacks using shrouded propellers in the airframe design. The company has also designed and made watercraft. Trek Aerospace also assists companies in the design, fabrication, and licensing of projects involving shrouded propellers and/or autonomous control systems.
The company states their core technology has the highest thrust to hp/kw in the industry. This allows their aircraft to carry a lot of weight in a smaller footprint. Trek’s shrouded props require less power, use fewer batteries than other battery powered aircraft, have a greater payload and have a farther range.
The SoloTrek XFVM (Exoskeleton Flying Vehicle - Military) is a one passenger VTOL backpack "helicopter" which was originally to be powered by a rotary engine and had drive shafts and gear boxes to turn the variable pitch ducted blades. However, the company has stated this aircraft could be converted to a hybrid-electric VTOL aircraft or to an eVTOL aircraft. A project that could very well happen anywhere in the world by a Trek Aerospace or a military aerospace manufacturer. By retrofitting the aircraft with new eVTOL technologies that exist today, the aircraft would become lighter, safer, more stable, more flight worthy and be a more eco-friendly aircraft.
SoloTrek XFVM Mission Capabilities
Search and rescue
Parachuting the aircraft to stranded military personnel to help them escape enemy hands
The original estimated top speed of the backpack aircraft is 113 mph (180 kph) with a range of 184 miles (295 km). The an empty weight of the aircraft is estimated to be 375 lb (170 km) and can carry a payload of 358 lb (162 km). The maximum take off weight of the aircraft was originally estimated to be 834 lb (378 km). Of course, these are estimated specifications and all these specifications would change based on the aircraft having either a hybrid-electric or all-electric power source. By converting to electric motors, newer and lighter propellers and using battery packs would greatly reduce the complexity of the aircraft and lighten the weight of the aircraft.
The pilot's controls are two joysticks, one joystick is for direction and the other joystick to gain or lower the altitude. The aircraft is controlled by a fly-by-wire computer system that can tilt each fan individually to control pitch and yaw. If fitted with new eVTOL technology, the flight worthiness and control of the aircraft would be greatly improved. Looking at the artist's concept drawings, one can see the aircraft is outfitted with spot lights, can hold a soldier wearing military gear and has a holder for a military rifle.
The aircraft has two shoulder straps and a waist strap to secure the pilot to the fuselage. Two foot rests are located on the aircraft's fixed strut-type landing gear. Two counter-rotating ducted fans are located at the top of the fuselage on either side of the pilot which were originally to be powered by a 118 hp rotary engine. Counter-rotating the blades eliminates the torque of the variable pitch blades. The safety feature of the aircraft is a ballistic whole aircraft parachute that is fitted at the top of the airframe between the two ducted fans. The aircraft has tricycle type landing gear with two fixed wheels on the back of the landing making it easy for personnel to move the aircraft around when on the ground.
The SoloTrek XFV was first flown in December 18, 2001 when the company was called Millennium Jet Inc. It is unknown if the company is planning on making this aircraft into a production aircraft.
