A method for measuring take-off sjid landing performance of aircraft, using an inertial sensing system

The STALINS method for measuring take-off and landing trajectories is briefly described and results of flight tests made in 1978-80 are discussed. The method now meets the requirements to which it was designed, and a few improvements in the hardware and software are being finalized. The method is expected to be ready for operational use in the...

Analysis of possible interference in radio altimeters induced by a position marker system called RASP

An analysis is given of possible interference induced by a position marker system, called RASP, into aircraft radio altimeters. The RASP system is used as a marker beacon in flight tests for trajectory measurements, and operates on 4.3 GHz. It is concluded that radio altimeters will not experience any harmful interference from a RASP transmitter.

Two-dimensional flight-path reconstruction by means of spline approximation

In this report, a method is developed to reconstruct the flight-path of an aircraft in symmetric, non-steady flight by representing this path by a set of splines. That set of splines is chosen, for which the flighttest data are best explained in some weighted least squares sense. This leads to a large, sparse, nonlinear, overdetermined system,...

Parameter identification results of tests in non-steady symmetric flight with the Hawker Hunter Mk VII

This report presents the parameter identification results derived from data recorded during non-steady symmetric flight test manoeuvres with the Hawker Hunter Mk VII laboratory aircraft. This flight test program was executed in co-operation with the Department of Aerospace Engineering of the Delft University of Technology. The reproducibility of...

NLR Contributions to the flutter certification of aircraft with external stores

An outline is given of store flutter clearance activities of the NLR carried out by order of the Royal Netherlands Air Force. Special attention is devoted to the store flutter clearance of the F16 aircraft. Presented at: 7th Aircraft/Stores Compatibility Symposium,Wright-Patterson AFB, Ohio, 8-10 April 1986 and at the 17th Annual Symposium of...
