Due to significant advantages and successful applications, electric propulsion has become a key technology for both scientific and commercial space missions. Nowadays, almost every satellite is equipped with an electrical propulsion subsystem for the purposes of orbit transfer, orbit correction, collision avoidance, and performing stating-keeping maneuvers. Considering these advances in space propulsion technology, TUBITAK UZAY initiated a project to establish an electric propulsion test facility and develop a Hall thruster propulsion system (HALE Project). In the scope of the project, Turkey’s first qualification test model electric propulsion system has been developed in Turkey’s very first electric propulsion laboratory. The facility has all necessary equipment to test Hall Thruster systems up to 5 kW power. The developed Hall thruster propulsion system is optimized to be operated at 1350 W providing minimum 75 mN thrust and 1500 s specific impulse. The paper summarizes all related R&D activities and presents performance of the developed equipment.
Elektrikli itki, önemli avantajları ve başarılı uygulamalarından dolayı bilimsel ve ticari uzay görevlerinde kilit teknoloji haline gelmiştir. Günümüzde, hemen hemen her uydu, yörünge transferi, düzeltmesi, koruması ve çarpışmadan kaçınma manevralarını gerçekleştirmek amacıyla elektrikli itki sistemiyle donatılmıştır. İtki teknolojisindeki bu gelişmeleri dikkate alarak, TÜBİTAK UZAY, Türkiye’de elektrikli itki test altyapısı kurmak ve bir Hall Etkili itki sistemi geliştirmek amacıyla proje başlatmıştır (HALE Projesi). Projede, Türkiye'nin ilk yeterlilik modeli elektrikli itki sistemi Türkiye'nin ilk elektrikli itki sistemi geliştirme laboratuvarında başarıyla geliştirilmiştir. Tesis 5 kW güce kadar çalışan elektrikli itki sistemlerini test edebilecek tüm ekipmanlara sahiptir. Geliştirilen Hall tipi elektrikli itki sistemi 1350 W’ta çalışmak ve en az 75 mN itki kuvveti ile 1500 özgül itkiyi sağlamak üzere optmize edilmiştir. Bu makale gerçekleştirilen tüm ilgili ARGE faaliyetleri özetlemekte ve geliştirilen ekipmanların performansını sunmaktadır.
