Learjet 45
The Learjet 45 is a business aircraft from the Canadian aircraft manufacturer Bombardier. It is the first completely new aircraft from the Learjet since William P. Lear's first Model 23
A Learjet version with increased take-off mass and range is named 45 XR.
Development
The beginning of the development of the Learjet 45 was announced by Bombardier in September 1992. The first flight took place on 7 October 1995. On 22 September 1997, the aircraft was finally approved by the U.S. Federal Aviation Administration, FAA. The first delivery was followed in January 1998.
Although it looks similar, it has only 50 percent of the components with the model Learjet 35 together. The aim was to achieve the performance of the Learjet 35, the handling of the Learjet 31A, and on top of that a more spacious cabin than the competition. The aircraft has an EFIS Honeywell digital engine control ( DEEC ) and an APU in each basic amenities.
In June 2004, the Learjet 45XR was presented. This revised version is characterized by a higher takeoff weight, greater range, higher cruising speed and a greater rate of climb. The improvements were achieved through revised engines.
The construction of the Learjet is a project in which many companies are involved. Thus, the final assembly was done in the USA (Wichita ) at Learjet, but the company Short Brothers in Ireland built the hull and the Canadian company de Havilland Aircraft Company was responsible for the design and construction of the wings. All companies are part of the Bombardier group of companies. 2012 Bombardier introduced the successor models of the Learjet 40XR and 45XR Learjet 70 and 75 as before.
