A much-modified PZL Wilga STOL airplane showed at Oshkosh 2018 with unusual fuel tanks.
The modifier installed extra fuel tanks in the undercarriage legs! He started with a Wilga 2000 that already has wide-chord main landing gear fairings, then he installed a Pratt & Whitney PT6a-28 turboprop engine producing 680 horsepower. To handle the extra fuel consumption, he added fuel tanks inside the main undercarriage fairings.
At least one other Wilga 105 has been converted with a (Walter?) turboprop in Eastern Europe, but it retains the original - narrow chord - undercarriage fairings.
1 - header tank between firewall and instrument panel
2 - upper wing centre section (especially biplanes)
3 - inside wings
4 - tip tanks (Pazmany)
5 - fuselage belly
6 - behind cockpit
7 - drop tanks
8 - wing strakes (especially Rutan)
9 - horizontal stabilizer (airliners)
10 - vertical stabilizer (airliners)
11 - baggage compartment (RV-12)
12 - cargo compartment (ferry tanks)
Can anyone think of any other place to install fuel tanks?
