Powered by a [Hispano-Suiza 8Fb](/source/Hispano-Suiza_8) inline piston engine driving a pusher propeller, the engine was strut mounted between the wings. The CAMS 31 was armed with two fixed hull-mounted [Vickers machine-gun](/source/Vickers_machine-gun)s in the bow. The CAMS 31 prototype, later designated the CAMS 31 Type 22, first flew in 1922. A second prototype, the CAMS 31 Type 23, flew in 1923 with a reduced-span wing and wider chord but still had the same wing area as the Type 22. Testing proved the flying-boats handled well but were just not suitable as fighters and no more were built. A mail carrying postal variant was designated CAMS 31P ==Variants== ;CAMS 31 Type 22 :Original wing ;CAMS 31 Type 23 :Reduced span extended chord wing of same area ;CAMS 31M:Proposed production fighter, not proceeded with. ;CAMS 31P :Postal variant ==Specifications (CAMS 31 Type 22)== {{Aircraft specs |ref= |prime units?=met |genhide= |crew=1 |capacity= |length m=8.80 |length ft= |length in= |length note= |span m=11.20 |span ft= |span in= |span note= |upper span m= |upper span ft= |upper span in= |upper span note= |mid span m= |mid span ft= |mid span in= |mid span note= |lower span m= |lower span ft= |lower span in= |lower span note= |swept m= |swept ft= |swept in= |swept note= |dia m= |dia ft= |dia in= |dia note= |width m= |width ft= |width in= |width note= |height m=3.05 |height ft= |height in= |height note= |wing area sqm=33.00 |wing area sqft= |wing area note= |swept area sqm= |swept area sqft= |swept area note= |volume m3= |volume ft3= |volume note= |aspect ratio= |airfoil= |empty weight kg=1045 |empty weight lb= |empty weight note= |gross weight kg= |gross weight lb= |gross weight note= |max takeoff weight kg=1505 |max takeoff weight lb= |max takeoff weight note= |lift kg= |lift lb= |lift note= |more general= |eng1 number=1 |eng1 name=[Hispano-Suiza 8Fb](/source/Hispano-Suiza_8) |eng1 type=inline piston engine |eng1 kw= |eng1 hp=300 |eng1 kn= |eng1 lbf= |eng1 note= |power original= |thrust original= |eng1 kn-ab= |eng1 lbf-ab= |prop blade number= |prop name= |prop dia m= |prop dia ft= |prop dia in= |prop note= |perfhide= |max speed kmh=200 |max speed mph= |max speed kts= |max speed note=at sea level |max speed mach= |cruise speed kmh= |cruise speed mph= |cruise speed kts= |cruise speed note= |stall speed kmh= |stall speed mph= |stall speed kts= |stall speed note= |never exceed speed kmh= |never exceed speed mph= |never exceed speed kts= |never exceed speed note= |minimum control speed kmh= |minimum control speed mph= |minimum control speed kts= |minimum control speed note= |range km=400 |range miles= |range nmi= |range note= |combat range km= |combat range miles= |combat range nmi= |combat range note= |ferry range km= |ferry range miles= |ferry range nmi= |ferry range note= |endurance= |ceiling m= |ceiling ft= |ceiling note= |g limits= |roll rate= |glide ratio= |climb rate ms= |climb rate ftmin= |climb rate note= |sink rate ms= |sink rate ftmin= |sink rate note= |lift to drag= |wing loading kg/m2= |wing loading lb/sqft= |wing loading note= |disk loading kg/m2= |disk loading lb/sqft= |disk loading note= |power/mass met= |power/mass imp= |power/mass note= |thrust/weight= |thrust/weight note= |more performance= |guns= 2 × fixed bow-mounted [Vickers machine gun](/source/Vickers_machine_gun)s }} ==See also== {{aircontent |see also= |related= |similar aircraft= |sequence= |lists= *[List of flying boats and floatplanes](/source/List_of_flying_boats_and_floatplanes) }} ==References== {{commons category|CAMS 31}} ===Notes=== Orbis 1985, p. 999 ===Bibliography=== {{refbegin}} *{{cite book |title= The [Illustrated Encyclopedia of Aircraft](/source/Illustrated_Encyclopedia_of_Aircraft) (Part Work 1982-1985)|publisher= Orbis Publishing}} {{refend}} {{CAMS aircraft}} Category:Flying boats Category:1920s French fighter aircraft 31 Category:Single-engined pusher aircraft Category:Biplanes --- Adapted from the Wikipedia article [CAMS 31](https://en.wikipedia.org/wiki/CAMS_31) by Wikipedia contributors ([contributor history](https://en.wikipedia.org/wiki/CAMS_31?action=history)).
