Embraer ERJ145 is a type of regional jet aircraft manufactured by 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). The ERJ145 is the largest aircraft in the family. Each aircraft of this type has two turbofan motors. The main competitor of the ERJ 145 class is the CRJ class produced by 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 of 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

Due to the change in the appearance of the aircraft, there was a long delay in its preparation for production. At the same time, it was necessary to unify the newest aircraft with the EMB120Brasilia. However, the huge number of orders played a big role in the project's success.

Variations of plane

96 percent of ERJ140 parts are interchangeable with ERJ145, for the crews these aircraft are identical. Differences in shorter fuselage, certain changes in engine control and longer range. Embraer initially priced the ERJ140 at US $ 15,2 million. The ERJ140 development price is estimated at US $ 45 million. The ERJ135, which started in 1999, contains 95 percent of the parts, which are identical to the ERJ 145, but is 3,6 meters shorter.

ERJ145 has 50 seats, while ERJ140 was designed for 44 and ERJ135 for 37. ERJ140 was planned with a reduced number of seats due to the requirements of American aviation companies, which have an agreement with pilot unions for restrictions covering fifty local aircraft.

Embraer in 2003, created a joint venture with Harbin Aircraft Manufacturing Corporation from the Chinese city of Harbin. Harbin Embraer joint venture began production of the ERJ145 in partnership with other Embraer factories for the Chinese market.

Variations:

Civilian models

ERJ135ER - Longer range, based on 135 variations. This is ERJ145 with a shorter length, less passenger seats by thirteen, and is designed for only 37 passengers.

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

ERJ140ER - Shortened ERJ145, the number of passenger seats is six less, designed for only 44 passengers.

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

ERJ145STD - Basic model

ERJ145EU is a model for Europe. With the usual volume of fuel tanks 145STD (4174 kg), the maximum take-off weight (19990 kg) is higher.

ERJ145ER - Longer range.

ERJ145EP - With a fuel tank volume of 145ER (4174kg), the maximum take-off weight (20990kg) is higher.

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

ERJ145LU - With a fuel tank volume of 145LR (5187kg), the maximum takeoff weight (21990kg) is higher.

ERJ145MK - With a fuel tank volume of 145STD (4174kg), and a similar maximum takeoff weight, the maximum weight of the aircraft without fuel is greater (17700kg)

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

Legacy - Businessjet based on ERJ135.
