Aircraft performance

Can an aircraft operate safely? What are modern aircraft? A searchable database of aircarft with recognition and performance data. Skip to aircraft details. Aircraft Performance Database. You will find performance information on almost any general aviation aircraft that has been in production in the past years. You can find the plane you are looking for two ways. For a vehicle in steady, level flight, as in Figure 13.

Airplane performance can be defined as the capability of an airplane to operate effectively while serving a specific purpose. Two basic factors, or a combination of the two factors, contribute to positive climb performance in most aircraft: The aircraft climbs (gains PE) using excess power above that required to maintain level flight, or The aircraft climbs by converting airspeed (KE) to altitude (PE).

In this chapter we will make theconnections between aircraft performance and propulsion systemperformance. Any thrust available inexcess of that required to overcome the drag can be applied toaccelerate the vehicle (increasing kinetic energy) or to cause thevehicle to climb (increasing potential energy).

Starting with the consideration that performance theory is the defining factor in aircraft design, the author then covers the measurement of performance for the certification, management and operation of aircraft. This practical book discusses performance measures which relate to airworthiness certificates (a legal requirement), as well as those needed when compiling the aircraft performance manual for the aircraft.

Here we deal with a few of the most important performance measures including airfield performance, climb, and cruise. Flight performance analysis for prop-driven and jet aircraft is explore supported by examples and illustrations, many in full color.

MATLAB programming for performance analysis is include and coverage of modern aircraft types is emphasized. The text builds a strong foundation for advanced coursework in aircraft. Assuming a volume of air in static equilibrium, the aerostatic equation gives: dP = - ρgdh.

In the case of high humidity, the volume of air available for combustion is reduce causing losses in power in combustion engines. The central theme of this book is the energy metho which enhances understanding of the standard methods and provides accessibility to advanced topics.

The following sections describe how each of these may be calculated at the early stages of design, by combining fundamental calculations with statistical data from actual aircraft. Performance” is a term used to describe the ability of an airplane to accomplish certain things that make it useful for certain purposes. For example, the ability of the airplane to land and take off in a very short distance is an important factor to the pilot who operates in and out of short, unimproved airfields.

The performance of an aircraft is the product of its design capabilities in terms of aerodynamics, and environmental influences that affect these capabilities. APP computes the complete range of aircraft performance parameters over a user-specified range of altitudes, speeds and other variables. The software is designed for spee simplicity and flexibility in its use.

Performance charts allow a pilot to predict the takeoff, climb, cruise, and landing performance of an aircraft. Information the manufacturer provides on these charts has been gathered from test flights conducted in a new aircraft, under normal operating conditions while using average piloting skills, and with the aircraft and engine in good. Many factors affect how the plane flies: its weight, the atmospheric conditions, pressure, temperature, humidity, even the runway at takeoff.

Thus, reduced atmospheric pressure decreases aircraft performance in the following ways: Reduced atmospheric pressure alters the production of lift. Reduced density means lesser molecules of air flowing around. EU exit Please note that, in the event of UK participation in EASA and mutual recognition of licences and certificates ceasing, some CAA website content and application forms may continue to carry the EASA logo or reference the EU or EASA rather than the UK CAA in the short term.

Theoretical aircraft performance, obtained after manufacturing and flight testing, are described in flight manual. In aerodynamics, the flight envelope, service envelope, or performance envelope of an aircraft or interplanetary spacecraft refers to the capabilities of a design in terms of airspeed and load factor or atmospheric density, often simplified to altitude for Earth-borne aircraft.

Today, APP is a trusted aircraft performance analysis tool, unlike anything available in the industry today. High density altitude refers to thin air, while low density altitude refers to dense air.

Regardless of the actual altitude of the aircraft, it performs as though it were operating at an altitude equal to the existing density altitude. This course dives into the physics and phenomena that determine aircraft performance to give you practical insights for real-world aircraft operations and development of future aircraft designs. Although aircraft performance is important, systemwide performance is the overriding concern.

Without a systemwide perspective, research and development runs the risk of suboptimization—for example, by improving the performance of a vehicle system in a way that degrades overall performance of the air transportation system. In cooperation with Aerospace Publications we are proud to present the largest and most detailed aircraft information database on the Internet.
