Can some of you guys please tell me what the wing loadings are on your jets? 49 ozs./ sq. ft. sure sound high.

Thanks,
Tom

Not unusual at all. The two sport jets I have now go off in the low to mid 40's with full fuel. Three other semi-scale airplanes I had ranged from 65 to 75 at takeoff. Probably one of the reasons for the turbine waiver flight test is to demonstrate you can manage your energy with a highly loaded airplane. The sport airplanes are probably all towards the low end (say 30-45) while many of the scale birds reach some pretty high loadings.

As Thud Driver said, scale jets can have wing loadings much higher than the 49 ozs/ sq. ft. you are talking about. We are flying RC jets as aerodynamic test models and we have a PCM Models L1011 that we are flying at over 100 ozs/sq. ft. wet, and it flys fine. the dynamically scaled 757 model in the picture will fly in 3 months or so with a wing loading of 145 ozs/sq. ft.

I finished last year research program employing dynamically scaled down flying model - SHARV (Scaled High Angle Research Vehicle) with wing loadings around 130 ozs./ sq. ft. and size of typical turbine model: length 6.5 ft, span 4.2ft

Thanks for the replies guys. My concern is this is a small jet ( 42" span) And that 49 ozs. sq. ft. could go to 59 ozs. sq. ft. full of fuel. This is not taking any fusalage lift into account. We are flying a prototype and aside from sinking a little fast when you pull power out it doesn't seem as though it has that high of a wing loading.

Thanks again,
Tom

Pics please!

Marcin, more pics please too!

The trick with the high weight to lift ratio's is speed and power management. The MIG in the picture below even after a 9 - 10 minute flight still is above the 60oz per square foot level. There are very few turbine powered Jet models that are in the 40oz ratio's. Exactly why the higher level of experiance is necessary to fly Jet model aircraft more than one time without distroying them.

I did some quick calcs using the weights given in Top gun 2004, and based on the scaled down full size wing areas
F-100- 70 oz/Sq ft, L-159-85 Oz/Sq ft, Rafale- 55 Oz/Sq ft,
King Kat is 37 Oz/Sq Ft
B.V. Mig 15-50 Oz/Sq ft.
