BauAir Posted June 21, 2017 Share Posted June 21, 2017 (edited) I'm working on a 1/144th construction of the Hawker Siddeley HS.748 Srs.2a (also known as Arvo or BAe). One of my major problems are the airfoils, not the airfols themself, but the length of them. In the manuals, there is just the mean chord given with 8.231 feet (also the mean chord of the tailplane with 6.750 ft.). The t/4-sweep of the wing is shown in another documet with 2.92°, but nothing about the chord at the root or at the tip. Who can help? Thanks ahead!

BauAir Posted June 23, 2017 Author Share Posted June 23, 2017 Hello Dutch! Thanks, I own a copy if the maintenance manual, but that's all about of wing measurements ... I just need the two lines shown in my first post ... Regards, Quote Link to post Share on other sites
Dutch Posted June 24, 2017 Share Posted June 24, 2017 Do you have a set of Aviation News Plans Service line-drawings? Better yet, there is one on display in the UK. Can anyone just go and measure with a tape? From Wikipedia: "Avro 748 Srs 1 G-BEJD, c/n 1543 is preserved with the Speke Aerodrome Heritage Group at Liverpool John Lennon Airport, United Kingdom."

Dutch Posted June 24, 2017 Share Posted June 24, 2017 Or browse the Flight Global archive. Here is one example from 1960. Quote Link to post Share on other sites
BauAir Posted June 24, 2017 Author Share Posted June 24, 2017 Hello Dutch! Thanks, I browsed the "Flight Global Archive", wehre I found the 1/4-wing-chord: https://www.flightglobal.com/FlightPDFArchive/1967/1967 - 2267.PDF For all other basic informations I used this drawing (size: 14860 x 10918 pix), but it seams not to be the best ... because most lines are for the Andover, not for the civil 748 version. The background: In the maintenance manual are wing-flap-aileron-rib-stations shown, but this pages don't show any measurements from front to rear, just from the wingroot to the wingtip ...
