The '''Potez XV''' (also erroneously written '''Potez 15''') was a French single-engine, two-seat observation [[biplane]] designed as a private venture by [[Louis Coroller]] and built by [[Potez]] and under licence by [[Podlaska Wytwórnia Samolotów]] and [[Plage i Laśkiewicz]] in Poland.
==Design and development==
The aircraft was designed in the beginning of the 1920s by Henry Coroller in [[Potez]] works. It was a development of a [[Fighter aircraft|fighter]] [[SEA IV]] built by ''Société d'Etudes Aéronautiques'', a former firm of [[Henry Potez]] and Coroller. A [[prototype]] was flown in October 1921 and shown at [[Paris Air Show]] that year. It was conventional biplane with a fixed [[Conventional landing gear|tailskid landing gear]] and a nose-mounted 276&nbsp;kW (370&nbsp;hp) [[Lorraine 12D]] engine. The engine was later replaced by a 224&nbsp;kW (300&nbsp;hp) [[Renault 12Fe]].
After a successful evaluation, the aircraft was ordered by the ''Aéronautique Militiare'' as a [[Aerial reconnaissance|reconnaissance]] aircraft. The first aircraft were manufactured and delivered in late 1923.
Series-built aircraft were powered with [[Lorraine-Dietrich 12Db]] V-12 engines. 410 were built in France. The aircraft was built in two main military variants: '''Potez XV A.2''' reconnaissance aircraft and '''Potez XV B.2''' [[bomber]]-reconnaissance aircraft. A single [[prototype]] of a [[floatplane]] variant Potez XV HO.2 was built. There was also an export variant '''Potez XVII''' of 1923, built for Bulgaria only, with the same LD 12Db engine.
Already in 1923, Poland bought a licence for the Potez 15 and started to manufacture them in [[Podlaska Wytwórnia Samolotów]] (PWS, 35 built in 1925) and [[Plage i Laśkiewicz]] aircraft works (100 built in 1925-1926).
A development of Potez XV was [[Potez 27]],
==Operational history==
[[File:BASA-746K-1-84-10_airplanes_in_flight_Bulgaria_1930s.JPG|left|thumb|300px|Potez 15s in flight over Bulgaria, c. 1930.]]
Primary user of Potez 15s was the French Air Force, from late 1923. Main user became the Polish Air Force with 110 aircraft bought and 135 manufactured in Poland.
In the Polish Air Force, they were used from late 1924. Their withdrawal from combat units started in 1927, then they were used for [[Flight training|training]] until mid-1930s.
120 aircraft were sold to Romania, 12 to Spain, and eight to Denmark. Six Potez XVIIs were sold to  Bulgaria.<ref>{{cite web |url=http://aeroflt.users.netlink.co.uk/waf/bulgaria/bulg-af-all-time.htm |title=Bulgarian Air Force Aircraft Types - All-Time Listing |access-date=2007-07-03 |url-status=dead |archive-url=https://web.archive.org/web/20061013053326/http://aeroflt.users.netlink.co.uk//waf/bulgaria/bulg-af-all-time.htm |archive-date=2006-10-13 }}</ref> 25 Potez XV A.2 were used in Yugoslavia.<ref>[http://www.aeroflight.co.uk/waf/yugo/jkrv/yugo-af1-all-time.htm Yugoslav Air Force Aircraft Types]</ref> These shared the engine, [[fuselage]], [[Landing gear|undercarriage]] and [[Vertical stabilizer|tailfin]] of the Potez XV, combining them with the wings and [[Stabilizer (aircraft)|stabilizer]]s from a newer design, the [[Potez 25|25]].
==Description==
Wooden construction biplane with fixed landing gear. The fuselage was framed, with metal covering for front engine section, [[plywood]] covering for the midsection and canvas covering for the tail section. Rectangular two-[[Spar (aviation)|spar]] wings, plywood ([[leading edge]]) and canvas covered, of equal [[Wingspan|span]]. Crew of two, sitting in [[tandem]] in open [[cockpit]]s: pilot in front, observer in the rear. Conventional fixed landing gear, with a common straight axle and a rear skid. Engine in front, two barrel-type water Lamblin [[Radiator (engine cooling)|radiator]]s below the fuselage, between the landing gear. Two-blade wooden [[propeller (aircraft)|propeller]]. [[Fuel tank]]s in the fuselage. The pilot had one fixed 7.7&nbsp;mm (.303&nbsp;in) [[Vickers machine gun]] with an [[synchronization gear|interrupter gear]], the observer had twin 7.7&nbsp;mm (.303&nbsp;in) [[Lewis Gun]]s on a [[Scarff ring|ring]] mounting.
