TsAGI Scientists are getting closer to understanding the Shape of a Supersonic Business Jet

9 February 2015

TsAGI is working on the development of the shape of the upcoming supersonic business jet (SBJ). It is assumed that it will have expanded transportation features due to transformation of the first-class passenger cabin into economy class. According to the developers, this aircraft, compared with the first-generation supersonic airliners, will have a low level of sonic boom in cruise flight, which will enable operation over populated areas, and thus help to achieve greater economic and transport efficiency.

The work is carried out within the framework of the Federal Target Program, “Development of Russian Civil Aviation in 2002-2010 and for the period up to 2015.” The customer is the Ministry of Industry and Trade of the Russian Federation.

A series of studies carried out in TsAGI’s low-speed wind tunnel aim to examine the aerodynamic characteristics of the prospective SBJ during takeoff and landing. The tests produced baseline data to assess the stability and controllability of the aircraft at low speeds in a wide range of angles of attack and gliding angles.

TsAGI has been carrying out studies of the feasibility of creating prospective business and passenger supersonic commercial aircraft (SBJ/ SPJ) since the late ‘90s of the last century. The new generation of aircraft will be different from the first ones (Tu-144 and Concorde) in terms of higher aircraft performance and acceptable environmental performance. This upcoming aircraft must meet modern requirements and restrictions on atmospheric emissions and noise level in airport areas. According to the developers, compliance with prospective sonic boom restrictions and the potential of supersonic cruise operations over populated areas is one of the most important characteristics that determines the commercial feasibility of the project.

Currently, the supersonic passenger aircraft is in the stage of development of external appearance. By 2020, a bench engine can be developed, and in 2025 — a pilot (flight) sample of the product.

The new generation of transatlantic range SBJs will have a cruising speed of not less than 1,900 km/h, while modern airliners fly no faster than 900 km/h. It opens up great prospects for business and commercial aviation.
