Embraer ERJ145 is a type of regional jet aircraft of the Embraer, Brazil. The class includes models ERJ135 (37 passengers), ERJ 140 (44 passengers) and ERJ145 (50 passengers), as well as Legacy600 (business jet), and R99 (military version). ERJ145 - the largest in the family of aircraft. Each aircraft of this type has two turbofan engines. The main competitor of the ERJ 145 class is the CRJ class of release Bombardier (Canada).

Production aircraft family ends. Thus, in the first half year 2012 not produced any ekzemplyarasamolёta.

Project History

Earliest

ERJ145 was first introduced at the LeBurgé Air Show in 1989, as a variation of the EMB120 Brasilia, equipped with two turbofan engines. The main indicators of the proposed model were:

Engines placed on the fuselage.

Right wing.

75 percent parts are compatible with EMB120.

Flight range of 2500 kilometers.

Design Phase

Embraer engineers to 1990 years conducted tests using a wind tunnel, as a result of the design was largely changed in comparison with the EMB 120. New features:

The angle of the wing is 22.3 °.

Engines placed on the wing.

The maximum range is 2500 kilometers.

Production

A second test aircraft in a wind tunnel gave much better results, as a result it was decided to change the wing and move engines from the wing to the rear of the aircraft. The New Face of the aircraft was at the end of 1991 years, but for some time the project was shelved. Despite the large number of new settings from the aircraft EMB 120 inherited a number of technical solutions, including krnfiguratsiyu interior 2 + 1. The main features of the project are:

The engines in the rear of the plane

Wing sweep without endplates

T-shaped tail

Maximum range 2500 km

In connection with the change in the appearance of the aircraft was a long delay in its preparation for production. It was necessary to unify the most new aircraft with EMB120Brasilia. Nevertheless, a huge number of orders played a large role in the fact that the project took place.

Variations of plane

96 percent of parts ERJ140 replaced with ERJ145, for the crews of these aircraft are identical. Differences in a shorter fuselage, certain changes in engine control and a greater range of flight. At first, Embraer manufactured the price of ERJ140 in 15,2 million US dollars. The price of the ERJ140 development is estimated at 45 million US dollars. ERJ135, whose use began in the 1999 year, contains 95 percent details, which are identical to the ERJ 145, but it is shorter by 3,6 meters.

In ERJ145, 50 seats are provided, while ERJ140 is calculated on 44, and ERJ135 is on 37. ERJ140 planned with a reduced number of seats due to the requirements of the American aviation companies, which concluded an agreement with the pilots unions on restrictions applicable to fifty local aircraft.

Embraer in 2003, established a joint venture with HarbinAircraft Manufacturing Corporation from Harbin, China. Harbin Embraer joint venture, began production of ERJ145 together with other Embraer factories for the Chinese market.

Variations:

Civilian models

ERJ135ER - Longer range, based on 135 variation. This ERJ145 with a smaller length, less than the passenger seats at thirteen, is designed only for 37 passengers.

ERJ135LR - More range (improved engines and increased fuel tanks).

ERJ140ER - The shortened ERJ145, the number of passenger seats is less than six, calculated only on the 44 passenger.

ERJ140LR - More range (improved engines and increased fuel tanks).

ERJ145STD - Basic Model

ERJ145EU - model for Europe. With the usual volume of tanks with fuel 145STD (4174kg) more than the maximum take-off weight (19990kg).

ERJ145ER - More range.

ERJ145EP - When the volume of tanks with fuel 145ER (4174kg) more than the maximum take-off weight (20990kg).

ERJ145LR - More range (improved engines and increased fuel tanks).

ERJ145LU - When the volume of tanks with fuel 145LR (5187kg) more than the maximum take-off weight (21990kg).

ERJ145MK - With a volume of tanks with fuel 145STD (4174kg), and a similar maximum take-off weight more than the maximum weight of the aircraft without fuel (17700kg)

ERJ145XR - Longer range (numerous aerodynamic improvements, additional fuel tank (located aft) in addition to two large main tanks located in the wing (the same tanks as in the LR models), more weight, maximum speed and more powerful engines).

Legacy - BusinessJet based on ERJ135.

Military Model

C99A - Transport aircraft;

EMB145SA (R99 modelA) - Modification with AEW;

EMB145RS (R99 modelB) - Modification with FLIR and SAR;

EMB145MP / ASW - patrol marine modification.
