After recently delivering a Mirage to be converted, I toured the Jetprop factory at Rocket Engineering in Spokane, WA. It’s a really cool place where a lot of aviation magic occurs, so take the tour if you are ever close to the area.
As Jetprop owners can testify, on those cold wintry days, or when flying a super-high altitude, the back of the Jetprop cabin can get a little nippy, even with the heater at full-blast. So, Rocket Engineering came up with “SIL 14-560-02, Heat Exchanger Bypass System Installation”. It allows the bleed air from the engine to bypass the heat exchanger and be routed directly into the cabin, allowing for greater heat.
I thought this was a really nice installation, and it’s standard equipment on all Jetprop conversions in 2015 and beyond. Owners of earlier Jetprops can purchase the system by contacting Rocket Engineering (Doug 509/535-6445). Here’s a video that may help.
