General characteristics
※ Military avionics chassis include standard ATR aviation cases and non-standard custom aviation cases.
The external dimensions of the standard ATR aircraft chassis conform to the ATR external dimension series, and the internal structure is designed according to the actual use requirements of customers.
The shape and internal structure of the non-standard customized aviation chassis are designed according to the actual needs of customers.
※ Military aviation chassis has excellent performance in anti-vibration, electromagnetic shielding, heat dissipation and environmental protection, so as to adapt to various harsh environments of military equipment. According to different needs, different structural design schemes can make the chassis adapt to various use environments. Military aviation chassis is widely used in airborne, vehicle and shipborne fields.

Note: The above standards are for reference only. If there are other design requirements, the chassis can be designed according to the actual needs.
Otto Company designs and produces military aviation chassis with excellent performance in anti-vibration, electromagnetic shielding, heat dissipation and environmental protection, so as to adapt to various harsh environments of military equipment. According to different needs, different structural design schemes can make the chassis adapt to various use environments.
Lightweight chassis: Under the conditions of stricter weight requirements, the ultimate weight reduction can be achieved while ensuring the strength of the chassis
Heavy-duty chassis: structural design for large loads
Electromagnetic compatibility: According to the actual frequency of electromagnetic waves, special structures, materials and other designs are used to meet the requirements of electromagnetic shielding
Heat dissipation: When the power of the internal components of the chassis is relatively large, methods such as air cooling and liquid cooling are generally used to improve the heat dissipation efficiency.
Corrosion resistance: choose appropriate materials, use special structural forms and technological means, and the salt spray test can reach 192h
