The large flaps have stops at 15 degrees and 30 degrees, and may be pulled to 45 degrees for additional glidepath control. At the slower end of the speed range, stalls are accompanied by ample buffeting and a very honest nose-drop.Landing is straightforward as long as you remember that energy corrections don’t happen instantly. The PBS TJ100 is especially suitable for manned and unmanned vehicles. After switching on the master, instrument, engine, and aux pump switches, simply push the thrust lever forward. A small, spring-loaded stop pin prevents unintended further motion of the handle. I’ve also enjoyed the privilege of working with its designer, John Monnett; his wife Betty; son Jeremy (now CEO of Sonex Aircraft); and the rest of the Sonex Aircraft family.The SubSonex, which recently completed its test flight program, was built by Powering the SubSonex is the TJ-100 jet engine, produced by PBS in the Czech Republic. Fuel capacity will be around 42 gallons, and the landing gear will be electrically retractable. These engines are also ideal for gliders and light sports and experimental airplanes. Whether it was James Bond flying through a barn in Octopussy, the diminutive Coors Light Silver Bullet flying at an airshow, or simply the “Bullet-Nosed Beauty” on the cover of Popular Mechanics, the little jet invoked a unanimous response: cool!
It’s for those times when you just feel the need for speed.The reason behind most jet regulations is simple: Jets fly fast, high, and far; therefore, the pilots who fly them need special training. Its primary purpose is to establish the feasibility of the very, very light jet (VVLJ) concept. The disc brakes bring her to a stop in less than 1,000 feet.The SubSonex in its current form is technically not even a prototype, but more of a preprototype, proof-of-concept aircraft. Price is projected to be comparable to that of a new LSA, with a substantial portion of the kit’s cost going to the new PBS engine. A little nose up and she’s rocketing skyward at nearly 2,000 feet per minute. After all, you don’t see many piston singles with Mach meters in the upper flight levels, nor do you see many jets doing touch and goes for fun on a Saturday morning.The advent of small, reliable jet engines such as the TJ-100 will certainly smudge that line. Alas, the personal jet concept appeared to have gone the way of the dial telephone—or has it?Sonex Aircraft hopes to revive the coolness of the personal jet with the SubSonex. Primary control is by means of a sidestick and conventional rudder pedals. Already a member? The takeoff roll begins at a stately pace, but increases steadily to a rotation speed of 80 mph, at which time you become fully aware of the diminutive four-inch main wheels and lack of spring suspension. There is no room for golf clubs, suitcases, or even a large sack lunch—the SubSonex is all about taking you back to that adrenaline rush you felt when you first saw the BD–5J. Powering the SubSonex is the TJ-100 jet engine, produced by PBS in the Czech Republic.
After all, with no prop to clear, there is no reason to make it any taller. The TJ-100 turbine (jet) engine is based on the APU designs built for aircraft and helicopters. Their engines are suitable for UAVs, target drones and cruise missiles. The second word is fighter. When it’s time to come down, reducing power to 70 percent rpm while maintaining 140 mph provides an average descent of about 800 fpm.During the descent, a faint voice is heard. Since 2008 more than 650 units of TJ100 have been delivered.In the compressor intake there is a brushless starter generator, which enables the starting from the board network and power generating in course of the engine operation.The intake air is compressed in the radial compressor wheel, proceeds through radial and axial diffuser into the combustion chamber, where it is mixed with fuel sprayed by several fuel nozzles.
The pilot monitors the start sequence on the digital display unit. Pushing in this pin slightly with the thumb allows the thrust lever to continue forward to the start/idle position, commanding the auto start sequence to begin.As the engine spools up, the controller begins firing the igniter and metering fuel automatically. The PBS TJ100 jet engine was developed for UAVs, missiles, light sport aircraft and gliders with an additional engine.
Aircraft Owners & Pilots Association Find it free on the storeWhat aviation enthusiast can forget the first time they saw the BD–5J? It’s not ATC or the headset’s Bluetooth link. All this takes about 20 seconds.In essence, flying a small jet is like driving a car that only has fifth gear.
The fuselage tapers to a “Y” tail (a “V” tail with a small sub-rudder for added yaw control). A ballistic parachute will eliminate the need for a personal chute, adding even more room to the cockpit.
