| 释义 |
Imperial German Navy seaplane number 947 was a reconnaissance aircraft produced during the First World War, the sole example of its type.[1][2][3] It was one of only three armed aircraft built by the Kaiserliche Werft Wilhelmshaven amongst a variety of trainer seaplanes that they had produced for the Navy during the course of the war.[1] Number 947 was a two-bay biplane of conventional design, with twin pontoon undercarriage, and two open cockpits in tandem.[1][2] It received the Naval classification CHFT,[3] indicating an armed aircraft equipped with radio gear capable of both sending and receiving.[4] The design bore a resemblance to a pair of trainer seaplanes produced at Wilhelmshaven (Nos 461–462) and to a design from Kaiserliche Werft Kiel (Nos 463–466), and all three designs could have been the work of the same designer or designers.[1] The machine was evaluated by the seaplane testing unit (SVK – Seeflugzeug-Versuchskommando) at Warnemünde at some point, but the records that have survived are somewhat contradictory.[1] In any case, no further examples were constructed.[1][3] Specifications{{aerospecs|ref=Kroschel & Stützer 1994, p.145, Gray & Thetford 1962, p.451 |met or eng?=met |crew=Two, pilot and observer |capacity= |length m=13.00 |length ft=42 |length in=8 |span m=15.95 |span ft=52 |span in=4 |swept m= |swept ft= |swept in= |rot number= |rot dia m= |rot dia ft= |rot dia in= |dia m= |dia ft= |dia in= |width m= |width ft= |width in= |height m=4.00 |height ft=13 |height in=2 |wing area sqm= |wing area sqft= |swept area sqm= |swept area sqft= |rot area sqm= |rot area sqft= |volume m3= |volume ft3= |aspect ratio= |wing profile= |empty weight kg= |empty weight lb= |gross weight kg= |gross weight lb= |lift kg= |lift lb= |eng1 number=1 |eng1 type=Mercedes D.IV |eng1 kw=160 |eng1 hp=220 |eng1 kn= |eng1 lbf= |eng1 kn-ab= |eng1 lbf-ab= |eng2 number= |eng2 type= |eng2 kw= |eng2 hp= |eng2 kn= |eng2 lbf= |eng2 kn-ab= |eng2 lbf-ab= |perfhide=Y |max speed kmh= |max speed mph= |max speed mach= |cruise speed kmh= |cruise speed mph= |stall speed kmh= |stall speed mph= |range km= |range miles= |endurance h= |endurance min= |ceiling m= |ceiling ft= |g limits= |roll rate= |glide ratio= |climb rate ms= |climb rate ftmin= |sink rate ms= |sink rate ftmin= |armament1=1 × trainable 7.9 mm machine gun |armament2= |armament3= |armament4= |armament5= |armament6= }}{{aircontent |see also= |related= |similar aircraft= |lists= }} Notes1. ^1 2 3 4 5 Nowarra 1966, p.78 2. ^1 Gray & Thetford 1962, p.450 3. ^1 2 Kroschel & Stützer 1994, p.145 4. ^Kroschel & Stützer 1994, p.113 References
