AeriaGloria Posted December 29, 2022 Share Posted December 29, 2022 (edited) Always thought it would be useful to have a drag index for JF-17. The recent discussion about pylons got me searching for what I could find. Can’t find drag added for bombs, only missiles and smart munitions and pylons Of note, can’t find drag added for fuel tanks or SPJ. I think I will have to do some drag tests and find a relative value. What I can find is…… DL pylon: 0.0015 BRM-90 pylon: 0.002 C-802 pylon: 0.0023 GB-6 pylon: 0.0024 SD-10 single pylon: 0.00086 SD-10 dual: 0.001126 Fuel tank pylon: 0.0014 SPJ pylon: 0.00064 SD/LD-10: 2 GB-6: 10 C-802: 8 LS-6 250/500: 8 PL-5: 1.6 C-701: 1.7 BRM-90: 3.6 Atleast this way for air to air we can make up an approximate drag index value for when we punch the fuel tanks. My usual 4x SD-10 and 2x PL-5eII would add 8.2 and some change. Really wish I could find SPJ/WMD-7/DL/fuel tank/bomb figures I would assume fuel tanks would be around same figure as C-802/GB-6. And if PL-5 and C-701 hover under 2, can’t see how SPJ would be more then about 2.

Napillo Posted December 30, 2022 Share Posted December 30, 2022 Shouldn't the SD-10 mass be 180kg? It's 199 in this one. Link to comment Share on other sites More sharing options...

I have seen varying statistics. 180 kg is a common value, so at first I thought 199 in LUA was wrong. Then I came across SD-10 placards from China that also states 199 kg. It makes sense if you compare it to sparrow weight, I can’t find the image, but it’s from Zuhai airshow. http://defenseupdates.blogspot.com/2012/11/sd-10a-and-ld-10-missiles-at-zhuhai.html?m=1 If you look at many sources, you will find lots of disagreement. But 199 kg seems to be straight from Zuhai promotional material Black Shark Den Squadron Member: We are open to new recruits, click here to check us out or apply to join! https://blacksharkden.com Link to comment Share on other sites More sharing options...
Napillo Posted December 30, 2022 Share Posted December 30, 2022 That looks like it's the weight with the mounting bracket included, based on the photos provided. Link to comment Share on other sites More sharing options...

That’s just how it’s displayed at the Zuhai airshow. The single pylon weighs 90 kg; and the double weighs 160 kg. So doesn’t fit the 20 kg difference 1 Black Shark Den Squadron Member: We are open to new recruits, click here to check us out or apply to join! https://blacksharkden.com Link to comment Share on other sites More sharing options...
