Following the success of the Learjet 25 series, the company embarked on experimental design ventures around 1970, opting to replace the CJ610 turbojet engine with the TFE 731. The outcome was a notable reduction in noise levels coupled with increased power. Rather than creating a variant of the 25 series, Learjet embraced this new design as the Learjet 35. The Learjet 35 served dual roles as both a business jet and a military transport aircraft, much like its successor, the Learjet 36. The most distinctive difference in the Learjet 36’s design was the enlarged fuselage tank, aimed at extending the range by 500 miles. However, this extension came at the cost of sacrificing nearly 20 inches in the passenger seating area.
Red Box is delighted to present an extensive range of ground power equipment tailored for the Learjet 35 aircraft. This includes tugs, ground power units, start power units and more, meticulously designed to meet the specific requirements of the Learjet 35.
Among our offerings are the 747C tug, and the RBSC150 continuous power unit—ideal for diagnostic work, pre-flight checks, or continuous powering of equipment during operations without depleting the onboard aircraft batteries. Additionally, the Twin RB75A is available for starting the aircraft, aiding in the prevention of hot starts. Our TC3000 range also provides a convenient combination of start and continuous power in one unit for the Learjet 35.
