1:72 EMBRAER EMB 320 A-27A ''Libélula", aircraft '7984' of 4º/3º GAv, Brazilian Air Force (Força Aérea Brasileira, FAB), Porto Velho Air Force Base/BAPV; during 'Operation Ágata', summer 2011 (Whif/Kit-bashing) by dizzyfugu, on Flickr


Some background
Seeking a domestic aircraft manufacturer, the Brazilian government made several investments in this area during the 1940s and '50s, but it was not until 1969 that Empresa Brasileira de Aeronáutica (EMBRAER) was created as a government-owned corporation. Born from a Brazilian government plan and having been state-run from the beginning, EMBRAER began a privatization process alongside many other state-controlled companies during the government of Fernando Henrique Cardoso. This privatization effort saw EMBRAER sold on December 7, 1994, and helped it avoid a looming bankruptcy.






The company's first product was a turboprop transport, the EMBRAER EMB 110 Bandeirante. In the course of years, both civil and military aircraft were developed, the focus shifted more and more to airliners, but the military work was never abandoned. The company continued to win government contracts, which included the EMB 314/T-27 Tucano trainer or the EMB 324/A-29 ground attack aircraft.

The EMB 320 was a bigger aircraft, though, and conceived in the early 2000s, when, with renewed economic stability, the Brazilian Air Force (Força Aérea Brasileira, FAB) underwent an extensive renewal of its inventory through several acquisition programs. The most ambitious of which was the acquisition of 36 new front-line interceptor aircraft to replace its aging Mirage III, known as the “F-X Project”.

In parallel, a supplement to the relatively new AMX fighter bomber (designated A-1 in Brazil) was needed, too, and this program ran under the handle “A-X Project”. While the F-X program was postponed several times until 2005, the A-X program made, thanks to its smaller budget needs, quick progress and resulted in the EMB 320 'Libélula' (Hornet), a dedicated ground attack, COIN and observation/FAC aircraft which would fill the gap between the AMX jets and various helicopters, e. g. the Mi-35M4 attack helicopter.






The EMB 320 was a straightforward design: a mid-wing two-turboprop-engined all-metal monoplane with retractable landing gear. Conceptually it was very similar to the Argentinian FMA IA-58 Pucara, but more sophisticated and with more compact dimensions. The aircraft was designed to operate from forward bases, in high temperature and humidity conditions in extremely rugged terrain. Repairs could be made with ordinary tools, and no ground equipment was required to start the engines.

The EMB 320 had a tandem cockpit arrangement; the crew of two were seated under an extensively glazed canopy on Martin-Baker Mk 6AP6A zero/zero ejection seats and were provided with dual controls. The pilot sat in front, while the rear seat would, if the mission called for it, be occupied by an observer, WSO or a flight teacher for training purposes. Armor plating was fitted to protect the crew and engines from hostile ground fire.

The retractable tricycle landing gear, with a double nose wheel and twin main wheels retracting into the engine nacelles, was fitted with low pressure tires to suit operations on rough ground and unprepared air strips, while the undercarriage legs were tall to give good clearance for underslung weapon loads. The undercarriage, flaps and brakes are operated hydraulically, with no pneumatic systems.
Through powerful high lift devices the EMB 320 could perform short takeoffs and landings, even on aircraft carriers and large deck amphibious assault ships without using catapults or arresting wires. Additionally, three JATO rockets could be fitted under the fuselage to allow extra-short take-off.






The aircraft was powered by a pair of Garrett T76-G turboprops, 1,040 hp (775.5 kW) each, driving sets of contra-rotating, three-bladed Hamilton-Standard propellers which were also capable of being used as air brakes. The engines were modified for operating on soy-derived bio-jet fuel. Alternatively the engines would operate on high-octane automobile fuel with only a slight loss of power, too.
Fuel was fed from two fuselage tanks of combined capacity of 800 l (180 imp gal; 210 US gal) and two self-sealing tanks of 460 l (100 imp gal; 120 US gal) in the wings.

The “Libélula”, quickly christened this way due to its slender fuselage, straight wings and the large cockpit glazing, was highly maneuverable at low altitude, had a low heat signature and incorporated 4th generation avionics and weapons system to deliver precision guided munitions at all weather conditions, day and night.

Armament consisted of two fixed 30 mm (1.181 in) Bernardini Mk-164 cannons in the wing roots and a total of nine external weapon hardpoints; these included a pair of launch rails at the wingtips for AIM-9 Sidewinder AAMs (or ECM pods), four underwing pylons outside of the propeller radius and three underfuselage hardpoints. Chaff/flare dispensers in the tail section provided passive safety. The EMB 320 could carry more than 3.5 tons of external munitions, and loiter for three or more hours.

Avionics included:
● MIL-STD-1553 standards
● NVG ANVIS-9 (Night Vision)
● CCIP / CCRP / CCIL / DTOS / LCOS / SSLC (Computerized Attack Modes)
● R&S{RT} M3AR VHF/UHF airborne transceiver (two-way encrypted Data Link provision)
● HUD / HOTAS
● HMD with UFCP(Up Front Control Panel)
● Laser INS with GPS Navigational System
● CMFD (Colored Multi-Function Display) liquid crystal active matrix
● Integrated Radio Communication and Navigation
● Video Camera/Recorder
● Automatic Pilot with embedded mission planning capability
● Stormscope WX-1000E (Airborne weather mapping system)
● Laser Range Finder
● WiPak Support – (Wi-Fi integration for Paveway bombs)
● Training and Operation Support System (TOSS)






The prototype made its maiden flight on 2nd of April 2000. In August 2001, the Brazilian Air Force awarded EMBRAER a contract for 52 A-27 Libélula aircraft with options for a further 23, acquired from a contract estimated to be worth around $320 USD millions. The first aircraft was delivered in December 2003. By September 2007, 50 aircraft had entered service. The 75th, and last, aircraft was delivered to the FAB in June 2012.

While the Libélula has not been used in foreign conflicts the aircraft already fired in anger: One of the main missions of the aircraft was and is border patrol under the SIVAM program, and this resulted in several incidents in which weapons were fired.






On 3 June 2009, two BAF A-27A Libélulas, guided by an EMBRAER E-99, intercepted a Cessna U206G engaged in drug trafficking activities. Inbound from Bolivia, the Cessna was intercepted in the region of Alta Floresta d'Oeste and, after exhausting all procedures, one of the Moscarsos fired a warning shot from its 30mm cannons, after which the aircraft followed the Libélulas to Cacoal airport.
This incident was the first use of powers granted under the Shoot-Down Act, which was enacted in October 2004 in order to legislate for the downing of illegal flights. A total of 176 kg of pure cocaine base paste, enough to produce almost a ton of cocaine, was discovered on board the Cessna; the aircraft's two occupants attempted a ground escape before being arrested by Federal Police in Pimenta Bueno.

On 5 August 2011, Brazil started “Operation Ágata”, part of a major "Frontiers Strategic Plan" launched by President Dilma Rousseff in June, with almost 30 continuous days of rigorous military activity in the region of Brazil’s border with Colombia. It mobilized 35 aircraft and more than 3,000 military personnel of the Brazilian Army, Brazilian Navy and Brazilian Air Force surveillance against drug trafficking, illegal mining and logging, and trafficking of wild animals.






A-29s of 1°/3º Aviation Group (GAv), Squadron Scorpion, as well as six A-27A’s from 4°/3° GAv launched a strike upon an illicit airstrip, deploying eight 230 kg (500 lb) computer-guided Mk 82 bombs to render the airstrip unusable.
Multiple EMB 320 were assigned for night operations, locating remote jungle airstrips used by drug smuggling gangs along the border, and were typically guarded by several E-99 aircraft. The Libélulas also located targets for the A-29 Super Tucanos, allowing them to bomb the airstrips with an extremely high level of accuracy, making use of night-vision systems and computer systems calculating the impact points of munitions.

Zum Modell:
Entstanden ist die Libelle aus der Idee, aus einer OV-10 Bronco ein "normales" Flugzeug zu machen, ein modernes COIN-Gerät. In Brasilien fand ich einen plausiblen Nutzer/Hersteller.
Die Basis ist die Academy-Bronco, die umfangreich "retuschiert" wurde, so z. B. mit einem neuen Rumpf & Heck (von einer Matchbox Bf 110 und VIEL Spachtel, Seitenruder von einer 1:100 A-10 von Revell) oder Bug (Sensor-Einheit von einem AH-64). Die Tragflächen wurden runtergesetzt und aus dem vorhandenen neue Triebwerksgondeln gestrickt, das Fahrwerk ist ebenfalls neu aufgebaut, um zu den neuen Proportionen zu passen.

Anstrich und Markierungen sind authentisch/zeitgenössisch, auch wenn es die 4º/3º GAv als Staffel nie gab. Die zitierte Operation Agatá fand aber tatsächlich statt, und die Explosions-Bilder sind tatsächlich Pressebilder der Brasilianischen Luftwaffe!

Hi Dizzy,

Was dagegen wenn ich das mal ein paar Bekannten hier aus Brasilien zeige?
Ich fands super interessant mal was "heimisches" der FAB zu sehen, danke dir dafür!

Sind "normale" Modellbauer, keine Whif oder Sci-Fi, aber die meisten interessieren sich für Flugzeuge im allgemeinen
und einer von denen baut die sogar komplett scratch, 100% für modelle die es - zumindestens so - nicht zu kaufen gibt.

Gibt es da ne Möglichkeit das für nicht-foren mitglieder zu verlinken oder so?

LG
Flo

Hallo Flo,

nein kein Problem, gerne - Du kannst auf die Bilder Clicken, dann kommst Du auf meine FlickR-Webseite, wo die Bilder öffentlich hinterlegt sind; ich habe bei den ganzen Fotos nur die Bildunterschriften mit Links wegeditiert, um Zeichen zu sparen (leider ist das Limit hier mittlerweile bei 20.000 Zeichen/Post gesetzt - ich bin aber wohl der einzige, der das mit den Galerie-Einträgen ausnutzt... :pfeif:).

Zum Bilderset, wo die Libellula hinterlegt ist (nur die Beauty-Pics - etwas runterscrollen), geht es hier:

http://www.flickr.com/photos/dizzyfugu/sets/72157629758520649/

Auf den FlickR-Bildseiten gibt es dann unten rechts einen Button, über den man sich eine URL ziehen kann, um das Bild z. B. in anderen Foren zu posten, das müsste auch für Gäste zugänglich sein, bei mir ist alles öffentlich hinterlegt.


Teilweise lustig, welch positives Feedback man auf solche "Exoten" aus den betroffenen Ländern erhält - aber ich find' das gut, und dafür poste ich den Kram ja auch.  ;)

Nebenbei: wenn einer Deiner Brasilianischen Bekannten das ZUPI Magazin liest/bekommt - da war ich vor einiger Zeit sogar mit einigen Modellen drin abgebildet (war aber Mecha-Kram, keine Whifs).

Hab mir die Bilder abgespeichertt und bei Facebook (in unserer Gruppe) geposted.
Hab deinen flick-link mal als "credits" dazu geposted, für weitere Bilder usw :)

Bin auch mal gespannt was die davon halten, kann mir von "aber das hats ja gar nicht gegeben, was fürn quatsch" bis "wow, echt cool", alles vorstellen,
aber nach deren Reaktion auf meine Ma.K.s her, glaube ich eher an positive Reaktionen.

Ich finde deine WHIFS auf jeden Fall immer SEHR cool und freue mich auch wenn du deine max Zeichen ausnutzt! :)
