The Van's RV-7 and RV-7A are two-seat, single-engine, low-wing homebuilt airplanes sold in kit form by Van's Aircraft. The RV-7 is the tail-wheel equipped version, while the RV-7A features a nose-wheel.〔Vandermeullen, Richard: ''2011 Kit Aircraft Buyer's Guide'', Kitplanes, Volume 28, Number 12, December 2011, page 74. Belvoir Publications. ISSN 0891-1851〕 The RV-7 is the replacement for the RV-6 and is externally similar to the earlier model, with longer wings, larger fuel tanks and a larger rudder to improve spin recovery characteristics. ==Development== The designer of the Van’s aircraft line, Richard VanGrunsven, designed the RV-7 series as a replacement for the RV-6. The RV-6 itself was a two seat side-by-side development of the RV-4, which was, in turn, a two seat version of the single seat RV-3.〔Bayerl, Robby; Martin Berkemeier; et al: ''World Directory of Leisure Aviation 2011-12'', page 125. WDLA UK, Lancaster UK, 2011. ISSN 1368-485X〕 The RV-7 incorporated many changes as a result of lessons learned over the years in producing over 2,000 RV-6 kits. The RV-7 airframe will accept larger engines, including the Lycoming IO-360, up to . The RV-7 also has increased wingspan and wing area over the RV-6, as well as more headroom, legroom and an increased useful load. The RV-7 carries a total of 42 US gallons of fuel, up from 38 US gallons on the RV-6.〔 The RV-7 shares many common parts with the RV-8 and RV-9 which reduces production costs. The RV-7 also uses computer assisted design to produce a kit with pre-punched rivet holes, thus greatly reducing assembly time for the builder. Construction time is estimated at about 1500 hours for an average builder.〔 The RV-7A version features a hardened, solid steel nose wheel strut that fits into a tube welded to the engine mount. As in all nose-wheel equipped RV aircraft, the nosewheel is free castering and the aircraft is steered with differential braking, or rudder at higher taxi speeds. The brakes are conventional toe brakes. By November 2014, 1394 RV-7s and RV-7As had been completed and were flying. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Van's Aircraft RV-7」の詳細全文を読む スポンサード リンク
