 Posted: Sun Jan 03, 2021 3:39 am Post subject: Under cowl temperature data request |
 |
|
The temperature label on my Softstart has not registered its lowest indication i.e. the temp has been <72C. This is with blocked side gills (the side vents at the back of the top cowl). However, there is no lip seal around the airbox, so hot air can vent through the NACA duct in the top cowl, after shut down. Typically in flight, the temperatures in the proximity of the modules is about +20C on ambient (OAT), or up to +30C differential in climbout.
I don't see much point of a temperature limitation for the softstart; it's not flight-critical, although the boxes under it are, and aren't helped by intimately sticking the softstart on top!

Wondered if anyone had recorded any under cowl temperature data with particular reference to post engine shutdown. I believe the installation of ‘soft start units’ had a not to exceed limitation applied.
Many thanks in advance.

Classic cowling gills not closed, no cold box: Separate air temp inside cowling in addition to GRT OAT. Measured with GRT EIS/EFIS: under cowling at firewall close to battery: average 15C to
+20C above ambient temperature. Stickers on CDI never registered significant above temp.
500+hours over 7 years. 912 ULS SR3000 Woodcomp 2 blade.
