The '''Messerschmitt-Bölkow-Blohm Bo 105''' is a light, twin-engine, multi-purpose [[Engineering:Helicopter|helicopter]] developed by Bölkow of Ottobrunn, West Germany. It was the first light twin-engine helicopter in the world, and the first rotorcraft that could perform aerobatic maneuvers such as inverted loops.<ref name= "Moll 96">Moll 1991, p. 96.</ref><ref>[http://www.bredow-web.de/Luftwaffenmuseum/Hubschrauber/MBB_BO-105M/mbb_bo-105m.html looping capability] {{Webarchive|url=https://web.archive.org/web/20151117020246/http://www.bredow-web.de/Luftwaffenmuseum/Hubschrauber/MBB_BO-105M/mbb_bo-105m.html |date=17 November 2015 }} according to the German Air Force museum at Gatow</ref> The Bo 105 features a [[Engineering:Helicopter rotor#Rigid|hingeless rotor]] system, a pioneering innovation in helicopters when it was introduced into service in 1970. Production of the Bo 105 began at the then-recently merged Messerschmitt-Bölkow-Blohm (MBB).

The main production facilities for producing the Bo 105 were located in Germany and Canada; due to the level of export sales encountered, additional manufacturing lines were set up in Spain, Indonesia, and the Philippines.<ref>Moll 1991, pp. 103–104.</ref> MBB became a part of Eurocopter in 1991, who continued production of the type until 2001. The Bo 105 was formally replaced in Eurocopter's product range by the newer Eurocopter EC135.

==Development==
In 1964, development work began at Bölkow upon the helicopter that would become the Bo 105, although work on the hingeless [[Engineering:Helicopter rotor|rotor]] it would use had begun earlier.<ref name= "flight 1967">Rieck, Joan M.

The third Bo 105 prototype was equipped with the initial production standard MAN Turbo 6022 turboshaft engines; six pre-production Bo 105s were constructed for testing.<ref name= "flight 1967"/>

On 13 October 1970, the German Civil Aviation Authority certified the Bo 105; initial deliveries for the first customers, ADAC Air Rescue and the Bavarian State Police, took place shortly thereafter. In 1972, further type certification was granted by the Federal Aviation Administration (FAA) and the Civil Aviation Authority (CAA), enabling export orders from the United States and Britain respectively, which soon followed.<ref name= "euro 40"/> In 1972, an improved version of the rotorcraft with more powerful engines, the Bo 105C, was developed; this model quickly superseded the Bo 105A.<ref name= "euro 40"/> On 25 September 1973, the prototype Bo 106 performed its first flight;<ref name="JAWA76 p73">Taylor 1976, p. 73.</ref> the Bo 106 shared many similarities to the Bo 105, the principal difference being a widened cabin area, capable of seating three abreast in the front row and four abreast in the rear of the cabin. However, nothing further came of the Bo 106 project.<ref name="AI may76 p246">''Air International'' May 1976, p. 246.</ref>

In 1976, the Bo 105CB, equipped with more powerful Allison 250-C20B engines, was introduced. The Bo 105C was further developed to become the Bo 105CBS, the primary change being a fuselage stretch of 10 inches to meet American demand for emergency medical service (EMS) operations; this version was often referred to as the Bo 105 Twin Jet in the United States. US aerospace firm Boeing-Vertol served as a partner in the type's production and further development, and marketed the BO 105 in the US.<ref name= "wee 54">Weeghman 1975, p. 54.</ref><ref>[https://www.flightglobal.com/FlightPDFArchive/2004/2004-09%20-%200793.PDF "A Marriage that Lasted."] {{Webarchive|url=https://web.archive.org/web/20151117021139/https://www.flightglobal.com/FlightPDFArchive/2004/2004-09%20-%200793.PDF |date=17 November 2015 }} ''Flight International'', p. 30. 31 May 2004.</ref> The Bo 105 CB and the Bo 105 CBS variants were also subject to [[Social:Licensed production|license manufacturing]] agreements, leading to them being produced by the Philippine Aerospace Development Corporation in the {{wipe|Philippines}}, Indonesian Aerospace (IPTN) in Indonesia, and Construcciones Aeronáuticas SA (CASA) in {{wipe|Spain}} in addition to the main production line in Germany.<ref name= "euro 40"/>

In 1984, the Bo 105LS was developed with the enlarged fuselage of the Bo 105CBS combined with more powerful Allison 250-C28C engines to increase the maximum take-off weight as well as hot-and-high flight performance; the Bo 105 LS was manufactured under a cooperative arrangement with Eurocopter Canada.<ref name= "euro 40"/> Improvements and modifications to the Bo 105 LS continued until 1995.<ref name= "euro 40"/>

Production of the Bo 105 by Eurocopter formally ended in 2001, principally due to the type having been superseded by the more modern Eurocopter EC135, itself a direct development from the Bo 105. By the end of production, 1,406 rotorcraft had been manufactured and delivered to operators in 55 nations worldwide.<ref name= "euro 40">Gotzhein, Christina.

==Design==
[[File:MBB BO 105 engine.jpg|thumb|A view of a Bo 105's engine, transmission, and main rotor]]
The Bo 105 has a reputation for having high levels of maneuverability; certain variants have been designed for aerobatic maneuvers and used for promotional purposes by operators, one such operator in this capacity being professional pilot Aaron Fitzgerald, flying for Red Bull.<ref>{{cite web |url=http://www.redbullusa.com/#page=ArticlePage.1165622311204-62961151.0 |title=Sports & Entertainment News &#124; Teams & Athletes |publisher=Red Bull USA |access-date=19 December 2012 |archive-url=https://web.archive.org/web/20090428200138/http://www.redbullusa.com/#page=ArticlePage.1165622311204-62961151.0 |archive-date=28 April 2009 |url-status=live }}</ref><ref>Wise, Jeff.

Perhaps the most significant feature of the Bo 105 is its [[Engineering:Helicopter rotor|rotor]] blades and rotor head. The rotor system is entirely [[Engineering:Hinge|hinge]]less, the rotor head consisting of a solid titanium block to which the four blades are bolted;<ref>Moll 1991, pp. 98, 101.</ref> the flexibility of the rotor blades works to absorb movements typically requiring hinges in most helicopter rotor designs.<ref name= "Moll 101">Moll 1991, p. 101.</ref> The rotor blades are made from reinforced-plastic glass-fiber composite material; the flexibility of the main rotor allows for active elements other than rotor pitch changes to be removed, greatly simplifying maintenance and extending blade lifespan.<ref name= "wee 56">Weeghman 1975, p. 56.</ref> The reliability of the advanced rotor system is such that, in over six million operating hours across the fleet, there was a total of zero failures (as of 1991).<ref>Moll 1991, p. 98.</ref> The rigid rotor design adopted on the Bo 105 has been partially responsible for the type's agility and responsiveness; it remained an uncommon feature on competing helicopters throughout the Bo 105's production life.<ref name= "Moll 103">Moll 1991, p. 103.</ref>

Military operators would commonly operate the type at a very low altitude to minimise visibility to enemies, the Bo 105 being well matched to such operations, as the helicopter's flight qualities effectively removed or greatly minimised several of the hazards such a flight profile could pose to pilots.<ref>Moll 1991, pp. 102–103.</ref> When outfitted with optional auxiliary fuel tanks, a basic model Bo 105 had a flight endurance of roughly five hours under load.<ref name= "Moll 104">Moll 1991, p. 104.</ref> In the event of a single engine failure, the Bo 105 could typically continue its flight, albeit with a reduction in cruise speed and range.<ref name= "wee 56"/> Besides the two pilots, the cabin can be configured to accommodate up to three passengers on a single rear bench, which can be removed to make room for cargo or a stretcher, which can be loaded and unloaded via the large clamshell doors located at the rear of the fuselage.<ref name= "wee 57">Weeghman 1975, p. 57.</ref> In a maritime context, the BO 105 can be equipped with auxiliary [[Engineering:Fuel tank|fuel tank]]s, emergency flotation equipment, an inflatable life raft, folding rotor blades and high skid landing gear.<ref>[http://www.ccg-gcc.gc.ca/Fleet/Messerschmitt-Bolkow-Blohm-BO-105-CBS-Helicopter "Characteristics of the Messerschmitt-Bolkow-Blohm (BO-105-CBS) helicopter."] {{webarchive|url=https://web.archive.org/web/20151117022631/http://www.ccg-gcc.gc.ca/Fleet/Messerschmitt-Bolkow-Blohm-BO-105-CBS-Helicopter |date=17 November 2015 }} ''Canadian Coast Guard'', Retrieved: 6 November 2015.</ref>

==Operational history==
[[File:Bundesarchiv B 145 Bild-F073468-0003, Hubschrauber BO-105.jpg|thumb|German Army Bo 105, 1986]]

In 1975, the German Army decided to procure a specialist anti-tank version armed with up to six Euromissile HOT missiles, designated as the Bo 105 PAH-1 (Panzerabwehrhubschrauber: antiarmor helicopter). A total of 212 Bo 105 PAH-1s were delivered between 1979 and 1984.<ref name= "euro 40"/> German Army leaders saw the PAH-1 as a temporary measure only, having originally sought a more capable anti-tank helicopter; they were particularly dissatisfied with the PAH-1's inability to perform nighttime combat missions and its self-protection capabilities; ultimately, the [[Engineering:Eurocopter Tiger|Eurocopter Tiger]] was developed as a replacement.<ref>Krotz 2011, pp. 59–61.</ref> In 1977, the German Ministry of Defence selected the Bo 105C for its light observation helicopter (VBH) program, leading to the procurement of another 100 rotorcraft.<ref name= "euro 40"/> The helicopter was retired from German Army service on 13 December 2016, the occasion was marked by an 18-aircraft formation flyby from their base in Celle. The Bohicans, as their pilots were called, had clocked over 1.38 million flying hours.<ref name="aviationweek23dec16">[http://aviationweek.com/blog/last-bohicans Last Of The Bohicans] {{Webarchive|url=https://web.archive.org/web/20161229101927/http://aviationweek.com/blog/last-bohicans |date=29 December 2016 }} - Aviationweek.com, 23 December 2016</ref>

During the 1970s, MBB issued a license to produce the Bo 105 to Indonesian Aerospace (IPTN) as part of a wider agreement to help develop Indonesia's aviation industry. Within ten years, manufacture of the Bo 105 had been entirely localised within IPTN's own facilities.<ref>Amir 2012, p. 106.</ref> The Bo 105 has been used by various branches of the Indonesian National Armed Forces; military-operated Bo 105s have been reportedly used during the 1999 East Timorese crisis and the Papua conflict.<ref>[http://www.enaat.org/publications/stoparmind.PDF "STOP Arming Indonesia."] {{webarchive|url=https://web.archive.org/web/20160304070454/http://www.enaat.org/publications/stoparmind.PDF |date=4 March 2016 }} ''European Network Against Arms Trade'', 1994.</ref> Indonesian Bo 105s have also participated in several large-scale joint exercises.<ref>Keck, Zachary.

;Bo 106:Widened cabin to seat 7 instead of 5. First flight was on 26 September 1973.<ref>Flug Revue, issue January 1974, p. 4.</ref> A single helicopter of that variant has been made (registration D-HDCI, serial no. 84). The Bo 106 was also equipped with more powerful Allison 250 C 20B engines. In 1981, the German air rescue organization Deutsche Rettungsflugwacht/DRF Luftrettung bought that prototype and had it rebuilt into a 105 CB-2 with a standard cabin. It flew for DRF until November 1993 under the registration D-HCCC, but in 1994 it was put aside to gain spare parts for another DRF helicopter (Bo 105 CBS-S, registration D-HNNN, serial number 662).
