By the present time a great number of compounds and alloys with a shape memory effect has been known. The alloys based on titanium nickelide are the most widely spread. In space engineering there is a task of breaking a fuel conduit when separating the spacecraft from the rocket in space technology.The paper examines a procedure for design calculation of separating device of conduit using the Ti-Ni alloy (nitinol). This device can be used instead of the pyro-knives.The device contains two semi-rings from Ti-Ni alloy. In the place of break on the conduit an annular radius groove is made. At a temperature of martensite passage the semi-rings undergo deformation and in the strained state are set in the device. With heating to the temperature of the austenitic passage of bushing macro-deformation the energy stored by the nitinol bushing is great enough to break the conduit on the neck. The procedures for design calculation and response time of device are given.

The article describes questions of designing space vehicles landing devices which have energy absorbers constructed on the basis of polyfoams and cell structures.

The methodology of optimization of spatial orientation of cylindrical preparation is considered in view of its{her} deviations{rejections} of the form with the purpose of reduction of waste products at machining.

This article presents an experience of using magnetic materials in the space branch, which was saved up in Lavochkin Association.
