M-DOT INC. Specializes in Production of:

aircraft exhaust systems including -

turboprop aircraft exhaust systems, ducts, exhaust stacks, and eductor and ejector pipes

design, fabrication and repair of custom gas turbine exhaust ducts

thin wall stainless steel and inconel ducts

TIG welding to Mil-W-2219 and customer specs

stretch forming of thin wall compound shapes and elbows

With our 130-Ton hydraulic stretch press, we can stretch form stainless steel sheet metal parts at a lower overall cost than hydroforming for limited production runs. We also do rubber pad hydroforming on our hydraulic press. Shapes include: elbows for aircraft tailpipes and gas turbine exhaust systems, gores for dishes and curved flange sections. In our GTAW ( TIG ) welding department we can weld stainless steel and inco alloys in thicknesses down to .005 inch. We are ISO9001 qualified.

Complex prototypes and aircraft systems including

complete gas turbine engines for mav and uav use.

airflow ducting and measuring systems in stainless steel and inco alloys

venturi flow measuring sections

stainless steel manifolds

M-DOT INC. has a complete stand-alone engineering department specializing In:

design of complete gas turbine engines and turbomachinery including -

turbojets for unmanned vehicles and micro turbojets for micro air vehicles ( mav s)

turboprops for unmanned vehicles ( heavy fuel engines ) and micro turbine engines

small turbofans

Under US Government (DARPA, Army, Navy and Air Force) funding, we have internally developed a 94 horsepower twin spool turboprop for uav propulsion called the TPR80. The engine design can be produced in recuperated and non recuperated form. We are currently developing a micro turbine engine under DARPA funding that will propel micro air vehicles ( mav s). This engine can be configured as a variety of turbomachines including microturbojet, turboprop and turboshaft. Call or e-mail us today to quote your engine design program needs.

gas turbine engine components and laboratory systems including -

centrifugal and axial compressors

combustors and burners

radial inflow and axial turbines

gearboxes and reduction drives and associated shaft dynamics analysis

accessories including afterburners, thrust reversers and pumps

inlet bell mouths and flow measurement venturis

We have expertise in structural design and aerodynamic design of centrifugal compressors, axial fans and compressors, annular and can type combustors and burners, radial inflow turbines and axial turbines, turbine castings, impeller castings, high speed gearboxes and fluid pumps. We have also developed a specialization in microturbines, microcompressors and tiny burners. Our capable engineers are experienced in aerodynamics, foil bearings, shaft dynamics, stress analysis, and cycle thermodynamics. We are conducting research in the fields of ultra high speed turbine, alternator and electric motor development achieving speeds in excess of 500,000 rpm. Our goal is to reach a million rpm in a microturbine, motor or alternator

Other turbomachines and systems including -

small turbopumps for rockets and missiles

gas turbine exhaust noise suppressors and mufflers for aircraft and APUs.

tiny centrifugal compressors, microcompressors and tiny blowers

micro refrigerators and coolers

exhaust eductors and ejectors

stainless steel manifolds

We have produced and successfully tested a tiny jet fuel ramjet turbopump for the Navy capable of achieving 1300 psi output pressure at roughly 100,000 rpm. We have designed and fabricated a noise suppressing exhaust system for an APU that reduced back pressure yielding a remarkable increase in power.
