Original abstract

Abstract. The article describes compliance evaluation of a glider cockpit crashworthiness numerical simulation using a static test. The design of the test and the numerical simulation model were prepared in accordance with the CS 22.561(b)(2) requirements. The next part demonstrates a comparison of two crash test simulations to the hard and soft soil impact surface. Injury criteria were used to evaluate the simulations. The whole simulation was developed using nonlinear explicit transient dynamic computer code MSC. Dytran. Both the test and the simulations were carried out by the Institute of Aerospace Engineering, Brno University of Technology.

Czech abstract

Článek popisuje porovnání simulací dvou typů nárazových zkoušek kabiny kluzáku. První typ byl náraz kabiny z rozjezdu do poddajné dopadové plochy, druhý typ byl náraz do tuhé dopadové plochy po kyvadlovém volném pádu. Vyhodnocovanými a porovnávanými parametry byly vlivy nárazu na pilota formulované kritérii poranění. Verifikace konstrukce kluzáku byla provedena kvazi-statickou zkouškou podle požadavků předpisu CS 22.561. Simulace byly realizovány v explicitním systému MSC. Dytran. Simulace i zkouška byly uskutečněny na Leteckém ústavu VUT v Brně.
