Agusta A-109 "Hirundo"

Although Augusta has a solid track record for making helicopters designed by other companies, the A 109 Hirundo (Swallow) was the first mass-produced helicopter actually designed by the Italian company.

The sleek A.109 was originally intended to have a single 740hp Turbomeca Astazou XII turboshaft, but for additional safety it was redesigned in 1967 around two Allison 250-C14 engines.

Development of the A 109 was protracted, but the result has been satisfying. Large corporations, police departments and military users are pleased with its solid performance. For military and naval use, the Hirundo carries dozens of combinations of electronics gear, weapons and equipment. The hi-tech maritime A 109A ECM (electronic countermeasures) variant has a radar display, direction finder, electromagnetic emission analyser and jamming equipment.

A specialised military utility model, the A 109B, was proposed, but in 1969 this was abandoned in favour of the eight-seat A 109C civil version.

Agusta A.109M

Agusta began taking an interest in light turbine-powered helicopters in 1959 and developed a series of prototypes culminating in the A.105. Feasibility studies for a medium-capacity helicopter to succeed it — the A.109 — began in 1969, when many different designs were examined and the most promising subjected to thorough research. Wind tunnel tests, lasting almost a year, enabled the characteristics of the new helicopter to be greatly refined. Once the basic project had been drawn up, final design work of parts and equipment began in spring 1970, and in the summer detailed construction work was started.

The A.109 was originally intended to have a Turbomeca Astazou or UACL PT6B turbine engine, delivering about 700shp, but the A.109C (civil) version had the same four-blade rotor but a completely new fuselage, with clean, elegant lines. The powerplant was changed to twin 370shp Allison 250-C14 turbines and a retractable undercarriage was fitted.

The new aircraft was assembled in spring 1971; ground tests then took place, and the prototype made its first flight on 4 August 1971 from the Cascina Costa plant. It was piloted by Ottorino Lancia accompanied by Paolo Bellavita, who had developed the aircraft together with Bruno Lovera. Owing to a minor accident, testing was resumed some time later, in 1972, using the second prototype, as well as a special static test rig for the dynamic components. In 1973 a third prototype in military configuration was developed, together with a fourth model for civil use and an airframe for static tests.

The A.109 high-speed civil helicopter is in a class mid-way between the AB-206 and the Bell 212. It has a conventional configuration with a classic, four-blade articulated rotor, especially designed for fast flight. The rotor blades are of conventional honeycomb structure with a light alloy skin and extensive structural bonding. The carefully streamlined, compact fuselage consists of a broad, ventral shell in metal honeycomb with thin, light alloy panels designed to withstand the stresses from the cabin loads and shocks from the landing gear. The cabin can have various internal layouts, with pilot and crew seated side-by-side, two bench seats for two-three people, and a baggage compartment. Behind the cabin is the rear fuselage section which carries the landing gear units and fuel tanks. The retractable tricycle landing gear ensures optimum mobility on the ground and offers advantages in terms of reduced drag in fast flight. The fuel is distributed by electric pumps from two tanks with a total capacity of 550 liters. The two turbine engines are mounted side-by-side but are fully independent; breakdown of one does not affect the output of the other.

The five prototypes of the A.109 were certified in summer 1975. In fact, the Italian Aeronautical Register granted type approval to the A.109, the first twin-engine helicopter to be designed, developed and built wholly in Italy, on 30 May, shortly before the opening of the 31st Paris Aeronautical and Space Show. American approval followed two days later. In the meantime, production had already begun with five aircraft for evaluation by the Italian Army. Atlantic Aviation, then the American distributors of the Agusta 109, took out an option on 100 aircraft for the civil market at thesametime.

More recently, Agusta has introduced the Model A.109A Mk.II derivative, which has been substantially modified in the light of the flying experience of customers from 15 countries in all parts of the world. As a result engine-out performance has been improved at high altitudes, and in hot climates.

Agusta A-109 "Hirundo"

The basic Agusta A109A is notable as the first Agusta-designed helicopter to be built in large series, and is the end product of a special market analysis initiated in 1965. Initially envisaged for commercial use only, the A 109 was designed around a single 515kW Turbomeca Astazou XII turboshaft, but mainly for additional safety considerations, was redesigned in 1967 to take two 276kW Allison 250-C14 turboshafts. The projected A 109B military utility model was abandoned in 1969 in favour of the eight-seat A 109C Hirundo (Swallow) civil version, the first of three prototypes flying on 4 August 1971. Protracted trials, minor alterations and other factors caused unforeseen delays and the first A 109 pre-production aircraft was not completed until April 1975. Delivery of production machines, designated A 109A, started in 1976.

In addition to its designated role as a light passenger transport, the A 109A can be adapted for freight-carrying, as an air ambulance or for search-and-rescue tasks. It has proved a great commercial success, especially since the uprated A 109A Mk II was introduced, this featuring uprated transmission and 298kW Allison 250-C20B turboshafts. First delivered in 1981, nearly 200 had been built by 1989, following on from the 150 or so of the original model. From 1985 the Mk II has been available in a 'wide-body' configuration with bulged fuselage sides for greater comfort.

Non-civil roles proposed for the A 109A Mk II include light attack with TOW missiles or rocket pods, aerial scout, troop carrier, electronic warfare, police work and naval missions. In addition, the helicopter can carry two Mirach RPV drones for battlefield surveillance.

More potent military versions are the A 109 EOA and A 109K. Both feature fixed undercarriage and a lengthened nose. The A 109 EOA has been ordered for the Italian army as an observation platform, powered by the Allison 250-C20R engine. The A 109K has two 538kW Turbomeca Arriel IK turboshafts for hot-and-high operations. This armed multi-role machine flew for the first time in April 1983, but no orders have been forthcoming.

Dear A /C / Helicopter Operator,

My name is Yosi and I am a retired Air Force officer specialized in aircrafts engines and logistics.

In a period of economic crisis as the world faces now, it seems to be reasonable that companies are looking for alternatives in order to reduce their expenditures; therefore, I would like to offer you my assistance as follows:
*Finding overhauls and repair facilities for your turbo shaft / turbo prop engines & modules.
*Finding engines and modules for rent or exchange.
*Finding major engine spare parts in N /F, O /H or A /R condition.
I don't charge commission from A /C owners and operators.
Please don't hesitate to contact me.
