Raven Rotor Of Boulder Colorado had a display at Airventure 2006. They also hosted a number of free educational seminars for ultralight, experimental and light sport aircraft builders on the Suzuki/Geo auto engine conversions.  | 1300SV 90HP more vertical version of the 1300CC Geo®/Suzuki® auto engine | Raven now has a "Flat 4" ninety horsepower engine which can be used as a power plant in aircraft that would normally have a Rotax 912 engine installed in them. This year Raven introduced two new drives to allow for installation of the "Flat 4" on more aircraft. The 1300 SV allows for a more standard style engine mount with the engine sitting at about a 35% angle with the drive facing straight up and down. This allows the drive to sit right inside the intake manifold. The drive can be used both a tractor and pusher configurations. The 1300 SV "Sidewinder" has the engine sitting in a horizontal position, with the drive coming in from the side to the center of the engine. The Raven system uses the 1.3 liter, 1300 cc, 16 valve, Metro Geo or Suzuki Swift automotive engine. The engine with reduction drive weighs in a 175 lbs. dry. It produces 90 HP and 450 lbs. of static thrust at sea level, using the standard 2.26 to 1 reduction drive, with a 68 to 72 inch propeller. Cruise RPM is 4200 to 4600, which gives a fuel burn of approximately 2 gallons per hour. The engine tops out at 5500 rpm. This is the same RPM used by the engine when it is installed in a car and driving down the road. The engine weighs in about 15 lbs more than a Rotax 912 80 HP, but provides an additional 10 horsepower. This makes it ideal for aircraft like the Zenair 601, 701, Rans S6 Coyote, SkyRanger, Savannah, powered parachutes, and trike applications. For powered parachute installations a 2.5 to 1 ratio is recommended. Customers purchasing the redrive kit from Raven and sourcing out their own engine from a recycler or re-manufacturer will spend approximately half the price of a new Rotax engine. In the case of the new Turbo Version, it will come in at approximately 1/3 the cost of a Rotax 914. The engine has a proven track record in the automotive and aviation field. Raven currently has over 200 units flying with thousands of hours on them. Parts are readily available world wide. |
