rotax 915is problems

13:14 09-Th12-2020

Rotax surprised everyone by introducing the 912 iS in 2012, then followed that with a Sport model that has improved induction for higher takeoff torque. One of these is the French company Issoire, whose APM 40 Simba is a test bed for the 915 iS. Happy New Year Everyone! More familiar is the Progressive Aerodyne Searey, which is also a test-bed aircraft in a joint effort between Rotax, MT Propeller and RS Aerotech, which is developing an engine monitoring unit specifically for the 915 iS. Oil Temp Issues? This website contains many older reviews. We timed the 914-powered aircraft at about 13 seconds, while it was 11 seconds for the 915 iS airplane. Five of the engines didn't make it even 1/2 way to TBO (these are naturally aspirated Rotax engines - 100 hp 912 I believe). There’s a yin and yang to the numbers here, which is to say pluses and minuses. This is .724 hp/lb. Progressive Aerodyne has fielded about 700 Seareys, most experimentals but some LSAs, too. In the Searey, for example, the engine is installed as a pusher and has a substantial water radiator with a scoop and a fan. Direct injection is new tech as far as gas engines go carbs have no place anymore and when I hear balance problems between carbs and icing trouble I call that low tech. Although the Rotax 900-series got a chilly reception in the 1990s because of its weirdness, it’s really not that weird. Installed weight will vary somewhat by installation. With full throttle at about 1500 feet, the airplane was indicating over 110 MPH and still had something left. No prices have been announced yet so we don’t know what the upsell price of a 915 iS-equipped airplane will be. As for efficiency, we don’t have reliable data on this yet. All engines have their glitches, some more than others, but good practice is staying with what is proven reliable and has a supply chain to back it up. They claim .73hp/lb. This is so because buyers have wanted it this way; a Star Trek flight deck propelled by a ‘59 Buick engine room. The dry weight of the 915is is listed at 186.4 lb (without fuel pumps, radiator and oil cooler). The new Sport Pilot rule makes flying affordable! It’s not so simple as this, however. Please, advertisements for Viagra will be promptly deleted! The 912 iS has the same 100 HP as the 912 ULS, but it offers fuel injection and improved electronic engine management that make it substantially more efficient than the ULS. The 915iS is a turbocharged engine and will make full power (141hp) to 15,000ft. Andy is right. Meanwhile, once the engine is approved and in production—which it is expected to be within two or three months—the company can offer it in the kit version of the Searey. and ROTAX factory in Gunskirchen, Austria. With the constant-speed prop, the 915 aircraft is faster—much faster. It also has forged rather than cast pistons whose bottom surfaces get additional cooling through oil spray.
