PROJECT TITLE: Dynamic Launching and Recovery Procedures from High Altitudes — DYLARPHA 

Coordinator: National Institute for Aerospatial Research and Development (INCAS) 

Partners: Research Centre for Aeronautics and Space – University POLITEHNICA-Bucharest, CCAS-UPB 

Period: 11 December 2012 – 11 September 2015

Project director: Sorin Stefan Radnef

Project team:

INCAS:

• 2 senior researchers with experience in applied and scientific research 
• 2 young researchers
• 2 new graduate engineers

CCAS-UPB

• 3 senior researchers with academic background
• 3 researchers with academic background

Description: Continue the works of a previous project regarding dynamic launching/ recovery

Launching procedure with a maneuver which realize a dynamical launch of the rocket, assuring dynamical conditions closely to those reached by a ground launched rocket having usual 3motor stages

New mechanical description of the entire flight procedure, focused to obtain an autonomous representation of the mechanical movement

Control laws generation for a flight mission with constraints using an approach based on analytical methods

Simulation computer code for the controlled flight evolution

Numerical and in flight tests (using adequate similarity criteria)

Project objectives:

• the development of the data base from the previous project related to the dynamic launch/ recovery 
• accurate definitions of the main conceptual problems and mechanical modeling  for the  evolution of a launching/ recovering technical system.
• statement and development of a solving algorithm for the flight mechanical model not depending of a coordinate system 
• simulations of controlled flight considering the main flight phases of dynamic launching and recovery
• experiments in similar flight maneuvers

Activities:

• WP1 – Concepts and Basic Research
• WP2 – Mechanical and mathematical model implementation for the controlled evolution of the launching-recovery system; simulations
• WP3 – Analysis and numerical tests to determine optimal trajectories and control laws
• WP4 – Functional model and validation tests
• WP0 – Project Management

Contributions to the STAR programme objectives:

• The method of dynamic launching/ recovery is a new concept with research potential
• Estimated results, if validated by flight tests, may define a way to rise the flight security and cost efficiency and so to become an objective for space projects
• The project objectives require sustained efforts and cooperation from researches and academics which are involved in activities to approach these objectives
• New flight mechanics model and control method of flight mission with constraints are a solid base for foundamental scientific and applicative results
• Young researchers and new graduates are involved in the project activities
