Aircraft Design Software

Aircraft Performance Program (APP) was created in 1981 by ALR Aerospace, in association with RUAG Aerospace Defense Technology, as a unique aircraft performance and preliminary design analysis program to aid in the conceptual and preliminary design of fighters, trainers and light aircraft. Today, APP is a trusted aircraft performance analysis tool, unlike anything available in the industry today. DARcorporation is proud to be the only distributor of ALR’s Aircraft Performance Program software and strongly recommend this widely used program for aircraft performance calculations. Aircraft Performance Program (APP) is a specialized software for aircraft performance analysis. 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 speed, simplicity and flexibility in its use. It provides users with useful quick-look (evaluate) functions for the examination of a wide variety of data e.g. thrust, fuel flow, lift, drag, SEP, turn rate, etc. APP is recommended for commercial aerospace & engineering companies, government offices and aeronautical engineering universities. APP is the perfect solution for:

• Practical and theoretical performance analysis
• Concept development and detail design
• Competitor performance analysis
• Flight test and Certification support
• Flight handbooks, Performance and Marketing brochures
• University teaching and instruction Suitable for Commercial, Civil & Military Aircraft, Turboprops, Gliders, Trainers, Business Jets & UAVs

Evaluate & Compare

Use APP to evaluate and compare the turn rate of different fighter aircraft, analyze the most efficient cruise conditions of a transport, or the best glide ratio of a powerless glider.

Mission Performance Analysis

APP will compute most mission profiles based on defined mission specifications. The types of mission flight phases (take-off, climb, cruise, loiter, descent, etc.) are suitable for Commercial, Civil and Military Aircraft, Turboprops, Gliders, Trainers, Business Jets and UAVs.

Metric & British Units

APP works in metric and British units and is able to switch during program execution to either system. This feature allows a rapid conversion of results into either system of units. Due to its optimized numerical capabilities, the program solves performance calculations within seconds.

Full Mission Profile

A mission manager supports mission compilation and definition. Over 25 mission segments may be combined in any order for a full mission profile calculation. An optimizer routine evaluates the maximum range, maximum endurance and maximum operating range. Mission progress for user defined time steps and output parameters are printed to a spreadsheet and visualized with charts.

APP Benefits

Tested & Verified Commercial Software Product

Flexible

More than 60 output parameters are available for performance and mission evaluation. The output format can be changed without re-computation. Charts and spreadsheets may be copied directly into any Microsoft document or saved to file. For increased flexibility, the spreadsheets are compatible with MS Excel file format.

Easy integration

Aircraft Performance Program (APP) enables obstacle-free integration into existing working procedures. Existing in-house tools, procedures and methods may be kept to create APP models and the desired analyses.

Scalable

Aircraft Performance Program (APP) is a valuable tool for small design teams and large aerospace companies. APP will produce quick assessments without having to resort to internal, and very expensive, computer programs. Operators, research establishments, universities, government agencies and air forces will use it as a very cost-effective tool by avoiding expensive and lengthy subcontracting in many phases of their work.
