experimental aircraft supercharger

Our patented aircraft supercharger systems are F.A.A. In 2016 the 10-rib belt drive debuted along with more ADI flow; they resulted in a 282 mph qualifying lap. Because turbocharging, efficient as it is, brings heat and plumbing headaches many judge not worth the trouble in low- to mid-altitude aircraft. Engine management fell to another Canadian outfit, Ross Farnham’s Simple Digital Systems (SDS). approved for Cessna 182 E thru R models and Cirrus SR22. The red anodized ignition triggers are just visible behind the starter ring gear. Pages 369-371 have a couple of paragraphs that say: ... "Experimental version with turbo-supercharger. ... but “Y” was typically used for pre-production aircraft, while “X” was for experimental aircraft. The system is activated by rising manifold pressure; there is no manual backup. For over 100 years, this family-owned business has sold everything from pipe organs and PT-19 wings to high-performance parts for homebuilts. are mainly clustered to the left of the primary Garmin display. Recidivist hot rodders will recognize the supercharger as the popular, durable Vortech V1 centrifugal. That it can thump out far over 400 hp to the propeller backs up the posture. Bill Beaton chose a centrifugal supercharger for racing and cruising. Also obviously hand-crafted, first-generation stuff is the inlet tubing. “I complied by putting numbers on my airplane, and that was it.” After five or six races that year, Bill was the undefeated SARL Rocket champion and promptly retired (temporarily it turned out) from cross-country racing. Both Lycomings are boosted via Vortech centrifugal superchargers, giving us the chance to examine both 6- and 4-cylinder applications. Our directory also includes homebuilt aircraft, many of them built from popular aircraft kits. To please Canadian bureaucrats—who, like our own, seem happy to let you have a supercharger as long as you don’t use it (much)—boost was initially limited to 33-34 inches in 2015, making the Rocket little more than supernormalized. Why? Read More. “What other airplane can you fly at 240 knots and land at 50 knots? No down payment required. Pumping avgas and waxing flight school airplanes got Tom into general aviation in 1973, but the lure of racing cars and motorcycles sent him down a motor journalism career heavy on engines and racing. In 2015 he returned with the supercharger and ADI system, running 274 mph, limited by belt slippage due to the narrow 6-rib drive belt, along with relatively minor heat issues. Angle of attack indicators make better pilots and might save your life. Others available. Built for speed, not beauty, Bill’s Vortech-supercharged parallel-valve IO-540 projects a purposeful, engineering-centric personality. Canceling the XP-47J, attention turned to the XP-72 Ultrabolt, using a massive supercharged engine and two sets of propellers, the XP-72 hit a top speed of 490 MPH. He even offers a basic blower kit, but cautions it’s only for knowledgeable enthusiasts and is not user friendly. added 34 pounds to the empty weight. But, as with most of the advanced experimental fighters from the later days of WWII, the XP-72 was canceled in favor of fighter jet production. After enjoying the Rocket as is, Bill began improvements, and as is typical, he had some friends helping. If anything, at the current 40 gph of gasoline, Bill is nearing the flow limits of his Bosch fuel injectors, so he’ll have to upgrade those to safely support more power. It has no pressure or metering functions. And that’s a real shame! Two custom applications we just got a good look at were Bill Beaton’s 540-inch Harmon Rocket and Dan West’s parallel-valve IO-390-motivated RV-6. Zero down financing available for up to 15 years. approved for Cessna 182 E thru R models and Cirrus SR22. If so, which ones? To date initial ignition timing remains at 24 degrees BTDC; the SDS computer is tuned to retard spark 1 degree for every 3-inch rise in manifold pressure over ambient. Bill repurposed an automotive throttle body to achieve a sufficiently large boost bypass valve; the SCAT tubing ducts the bypass air aft to better direct it out the cowling exit. The thin air means a corresponding degradation in engine cooling, and with increased horsepower Bill’s 540 had more waste heat to shed. His system is from Devil’s Own, which offers bosses for AN fittings and gallon-per-hour rated nozzles, along with quality Teflon-lined hoses, robust pumps, and a progressive electronic controller. Bill logged about 850 hours in it, flying all over North America. Of course, there’s been weight creep since, so Bill’s currently chasing ounces where he can. It’s a bit of a shock to recall U.S. government research identified turbo-supercharging as the golden path to altitude compensation way back in 1918—and ever since the flying community has held turbocharging close. Learn how your comment data is processed. The idea of the turbocharger is to improve over a naturally aspirated engine's power output, due to the fact that the compressor can force more air—and proportionately more fuel—into the combustion chamber than atmospheric pressure (and for that matter, ram air intakes) alone. But the original SARL numbers are still on the fuselage. Experimental/Hybrid Aircraft for Sale : View our entire inventory of New Or Used Experimental/Hybrid airplanes and even a few new non-current models on AeroTrader.com. As expected, developing the supercharger is an ongoing, multi-year journey. It was naturally aspirated with 10:1 pistons and then-current avionics. Supercharging reduces weight per horsepower of the engines as required in aero engines. In fact, it was enough “to make you think it’s a fast airplane,” so in 2012 Bill raced the Rocket in the first Sport Air Racing League race in Coeur d’Alene, Idaho. Whereas a turbo system is powered by the engine's exhaust gases, a supercharger is powered by the engine itself, usually with a … Bill claims he’s personally shed a few pounds, too. XF4U-4: ... Supercharger was simplified for low altitude operation. While its characteristic stork-like gear legs give Bill’s plane the familiar Harmon Rocket stance, there’s nothing immediately suggestive of its nearly 300 mph straight-and-level potential to the casual observer. Bill’s 1998 Harmon Rocket II was built in Bakersfield, California, by Gary Banducci; in 2007 Bill imported it to his native Canada for sport flying. We are also an MT propeller distributor. For flight tests the supercharger was installed with a Liberty-12 engine in a modified DeHaviland-4 airplane, and an air-scoop on the side of the fuselage was connected with the supercharger intake. To performance-minded experimentalists, fabricating a relatively simple supercharger installation is easier and less maintenance intensive than working with turbochargers. favorite this post Dec 6 Hardigg air cargo pressurized rolling case $200 (DRIFTWOOD, TX 78619) hide this posting restore restore this posting. That was at 11,000 feet, where typical manifold pressure is 18-19 inches. Among the topics discussed are trim, pitch stability and yaw stability; © 2020 Kitplanes.com. The efforts of the Technical Division of Imperial Army Headquarters eventually culminated into the Tachikawa Ki-94-I, while the Ki-87 was developed as a fall-back project, … For example, our test Cirrus was fastest at 8000' in a cruise setting prior to the supercharger. If this place was an airport…a guide to airport personalities. Siemens–Schuckert Werke. We have a variety of experimental aircraft available from private owners and dealers that will provide you with a unique flying experience. That it can thump out … Bill’s fitment was the first SDS system to fit the electronic fuel injectors in the tappings normally housing Bendix fuel injectors, so his fuel is certainly shot closer to, and perhaps even through, the open intake valve and its seat than the more commonly seen intake runner mountings. In the meantime, his is a Harmon that really does rocket. Fully dedicated to digital engine management, Bill opted for a pair of SDS systems, complete with two electric fuel pumps, filters, and so on. Working with Aero Sport Power in Kamloops, British Columbia, goal one was durability under boost, so a fresh set of lightened Ly-Con NFS 8:1 pistons went in, along with a blower-specific Ly-Con camshaft.
