Melvin Schreiber

Title: Melvin Schreiber: Innovator in Aircraft Heat Exchanger Technology

Introduction

Melvin Schreiber is a notable inventor based in Roslyn, NY (US), recognized for his contributions to aircraft technology. He holds 2 patents that focus on enhancing air cycle performance in aircraft through innovative heat exchanger designs.

Latest Patents

One of Schreiber's latest patents is the "Anti-icing heat exchanger for aircraft air cycle performance enhancement." This invention utilizes unconditioned, sub-freezing turbine exhaust air to cool liquid coolant from radar electronics in an aircraft. The design incorporates a liquid/air exchanger that ensures the air-cooled heat exchangers do not freeze by supplying sufficient heat to maintain all surfaces above freezing. This innovative approach allows for significant savings in total cooling air flow by eliminating the need for a hot air bypass to reheat turbine exhaust air.

Another significant patent is the "Switchable heat exchanger configuration for air cycle cooling apparatus." In this design, a primary heat exchanger for heated bleed airflow is positioned upstream of an aircraft air conditioner compressor, while a secondary heat exchanger is located downstream. Under hot and humid conditions, three-way switching valves reposition the primary heat exchanger downstream, resulting in reduced heat exchange exit temperatures. This translates into lower turbine inlet and outlet temperatures, ensuring satisfactory airflow rates.
