Wing Loading

kwn idak ler tau banyak sgt pasal rc plane design nih. just basic consideration ja. n atas dasar apa yg kwn nak tau n perlu tau. so apa kwn jumpa masa reasearch tuk corostick rasa syg nak simpan sendiri. baik kongsi kat sini. untung2 ada yg sudi baca.



kwn rasa this one batter kwn put it in bahasa malaysia tuk rcer2 malaysia ja baca. heheheh … since da banyak guide tuk foreign rcer. kalu ader salah tolong komen.ni just ikut pemahaman sendiri.

semenjak berjinak ngan rc plane, kwn berangan nak design corostick (penangan nite stick bmnf). naper design n naper coro? sebab dari survey yg kwn wat, kwn xble transfer bmnf stick nyer measurement kat corostick, xsama berat (masa tu terpikir, naper plak? sama jer kan?). so sebab yg bg nasihat tu otai, n semangat nak hasilkan jugak corostick, kwn search for the answer kat internet.

why? wing loading. meaning, berat plane yg ditanggung setiap persegi wing.

camner nak kira? kwn refer byk pd american ngan europe nyer site, so mostly dorg pakai inch – in , feet – ft , ounce - oz, pound – lbs. so kwn pun terbawak-bawak n da selesa. ni calculator yg kwn pakai ni tuk convert - measurement

loading = wing area / all up weight (auw) plane

wing area = span (inch, in) x chord (inch, in)

auw = berat plane ngan bty (ounce, oz)



loading = auw x 144 / (span x chord)

naper darab 144 ? sebab unit tuk wing loading slalu dorg pakai ounce per square foot (oz/ sq ft) so because of span ngan chord kita dlm inch, nak memudah kan conversion, just darab ngan 144.

so ble nampak kat situ, berat plane dan luas wing memainkan peranan.

aper kesan dia atas plane?

ni basic numbers yg kwn dpt dr net:

less 1015 – trainer

20 – sport

25 – fighter



(in oz/sq ft. only apply tuk rc jer)

yup! low loading is batter for gliding.

so bmnf stick sebagai contoh dengan anggaran span 40”, chord 8” n auw 18 oz kita dpt:

loading = 18 x 144 / ( 40 x 8 ) = 8.1 oz/sq ft

so glider, mmg sah ler tu.

kita tgk kalu kwn guna same number tuk wing kat corostick kwn, but auw lebih kurang 750g = 26.5 oz:

loading = 26.5 x 144/ ( 40 x 8 ) = 11.9 oz/sq ft

masuk trainer nyer kategori. dan itu la yg jd ngan corostick version 1 kwn. ligat cam nemo with less glide.

aper kwn buat? try dptkan loading bwh 10. kwn design baru ngan wing yg lebe besar. span 50” n chord 10”. auw jd lebih sket dlm 850g = 30oz.

loading = 30 x 144 / ( 50 x 10 ) = 8.64 oz/sq ft

so it’s a glider. character glide ni la yg wat kwn jatuh cinta kat bmnf stick. so success and named it my corostickv2.

frm ape yg kwn faham dr research,  loading bukan define glide character ja. ngan tau loading kita ble agak brapa panjang runaway tuk take off n landing, brapa slow ble fly before stall.

low loading bagus tuk short take off n landing with low stall speed.

lain2 basic consideration tuk build plane, kwn cuba buat kalu rajin lg.
