Aircraft performance improvements a practical approach

Page 30 Share Cite Suggested Citation: The more recent report 1 identifies key technology challenges for supersonic business jets and two classes of larger commercial supersonic transports and 2 makes specific recommendations for research.

The National Academies Press. Key Points from Chapter Nine. Concepts of particular interest include 1 the strut-braced or joined wing and 2 the blended-wing-body BWB see Figure In this work, a review of those technologies which show a potential to deliver breakthrough improvements in the aerodynamic performance of the aircraft is shown.

The thick center section distinguishes the concept rather fundamentally from pure flying wing designs and leads to structural efficiencies that improve the overall performance of BWB aircraft.

Doing this will reduce induced drag, and increase your range and cruise airspeed. Currently, the operating cost per seat-mile for VTOL aircraft is 4 to 10 times higher than for conventional aircraft. Applying the Science of Improvement to Testing.

However, the ability to cruise at supersonic speeds is not without cost: Page 34 Share Cite Suggested Citation: Performance could be further improved by the ability to use turboprop propulsion and the option of hydrogen fuel because of the large size of super cargo aircraft, the low density of hydrogen fuel becomes less of an issue than it is with conventional aircraft.

However, they are not likely to capture an appreciable fraction of the commercial passenger market, even if technology is available to reduce the sonic boom to acceptable levels for overland travel.

Expanding the Expectations of Customers to Increase Demand. Laminar flow over the wings would further increase the efficiency of BWB aircraft—and of every other aircraft type discussed above.

Nonetheless, implementation of the process for change recommended by the committee see Recommendation would facilitate planning of research for all vehicle types. A plan view shows the wing as a rhombus, which gives the wing a rigid structure and allows it to have a greater span.

VTOL aircraft have the ability to provide passenger service without increasing demand for runway usage.


Testing and Learning Systems. However, such expressions of interest—no matter how vigorous—do not always result in a commercially successful product.

Subsonic transports benefit from design efficiencies unavailable to small aircraft, and they avoid design penalties associated with specialized capabilities such as supersonic cruise speed and vertical flight.

A Framework for Spread. Even with a MTOW on the order of several million pounds, the cruising altitude would be so low that a wing-in-ground-effect aircraft might be at risk from rogue waves.

5 Ways To Improve Your Aircraft's Performance

Blended-Wing-Body Aircraft BWB aircraft are a form of flying wings, a configuration that has been investigated by many different aircraft designers, manufacturers, and countries for over 50 years. Lighter-than-air vehicles cannot work at these altitudes because available solar energy is insufficient to overcome wind forces.

Methods for Developing Fundamental Change.Choosing the right altitude has a significant effect on aircraft performance. Normally aspirated engines lose power as they climb, due to the reduction in atmospheric pressure. The higher you climb, the more time it takes, and the more fuel you burn.
